Boarding (pushing or checking an opponent violently into the boards) and checking from behind are treated as serious safety infractions. Both carry a minimum minor penalty and may result in a major penalty plus a game misconduct, depending on the ...
Why people argue about this
People often assume that checking from behind is just about hitting an opponent with their stick, forgetting that it's also about pushing them into the boards or other players. In reality, the confusion arises because they overlook how positioning and intent matter; if a player checks another from behind but doesn't push them into anything, it might not be as egregious of a violation.
Each team designates one Captain (wearing a "C" on their jersey) and no more than three Alternate Captains (wearing an "A"). Only the Captain and Alternate Captains are permitted to discuss rule interpretations with the referee during the game.
Why people argue about this
People often assume that all players can discuss rules with refs if their team has Alternate Captains, misunderstanding that only the Captain and up to three Alternates are officially allowed to do so during games in ice hockey.
The NHL operates under a comprehensive concussion protocol developed in conjunction with the NHLPA. Any player suspected of sustaining a concussion is removed from play and evaluated by a team physician in a quiet room.
Why people argue about this
People think that players are just pulled from games randomly when they show signs of a concussion, but actually, it's a carefully managed process where only suspected concussions lead to removal, with immediate medical evaluation in a quiet room by a team doctor.
Assessed when a minor penalty infraction results in an injury to the opposing player (most commonly high-sticking that draws blood). The penalized player serves four minutes.
Why people argue about this
People think that double minor penalties are automatically assessed for high-sticking alone, without considering whether it caused an injury, but actually, it's only when a high-stick results in blood drawn that the penalty is extended to four minutes.
Any check in which the principal point of contact is the head of an opponent is prohibited, regardless of whether the head was targeted intentionally. Elbowing an opponent in the head is subject to severe penalties and supplementary discipline.
Why people argue about this
People often assume that elbowing is just fine if you don't hit the head directly, which leads to arguments about whether a check was intended to go for the head or simply missed by accident. The confusion arises because in ice hockey, even accidental hits to the head are penalized harshly under this rule, emphasizing its severity and seriousness regardless of intent.
All player equipment must meet standards established by the NHL and certified by recognized testing organizations. Helmets must be HECC-certified and properly fitted.
Why people argue about this
People often argue that it's too strict for players to only use HECC-certified helmets, thinking they need more advanced gear like exoskeletons or fancy suits. But actually, the confusion arises because this rule is about ensuring safety and reliability - not necessarily cutting-edge technology, which could be impractical or cost-prohibitive in professional play.
Play begins at the start of each period and resumes after each stoppage with a face-off. The visiting team's center places their stick on the ice first.
Why people argue about this
People think that a player can only be offside if they cross the blue line before the puck, but actually, it's about who crosses first - the puck or the player, regardless of which line they're on. The confusion arises because the rule emphasizes the timing aspect rather than location, leading to misinterpretations.
An NHL regular season game consists of three 20-minute periods of play with two intermissions of 18 minutes each. Each team plays 82 regular season games (the final season at this number before the planned expansion to 84 games beginning in 2026-27).
Why people argue about this
People often assume that each period is 20 minutes long without considering the intermissions, leading them to believe games are significantly longer than they actually are. The confusion arises because they overlook the fact that two intermission periods of 18 minutes each take away from the total game time.
A game misconduct results in ejection from the game. A match penalty is assessed for deliberate intent to injure and also results in ejection, with the matter referred to the NHL Department of Player Safety for potential supplementary discipline (fines or suspensions).
Why people argue about this
People often think that a match penalty is just for being ejected from the game, forgetting that it can lead to additional penalties like fines or suspensions handled by the NHL Department of Player Safety – which isn’t part of the initial ejection. They overlook the fact that these extra punishments are applied as supplementary discipline after the immediate expulsion.
A goal counts as one point for the scoring team. The player who shoots or last touches the puck before it enters the net is credited with the goal.
Why people argue about this
People often think that if a player accidentally touches the puck into their own net by mistake, it still counts as an invalid goal against them, but in reality, any player can score a goal regardless of where they touched the puck last before it went in, so even if someone scores an unintentional goal, it's still counted and awarded to that team.
A goal is scored when the puck fully crosses the goal line between the goal posts and beneath the crossbar, having been legally directed there by an attacking player's stick. Goals may also be scored by deflection off any part of a player's body other than a distinct kicking motion.
Why people argue about this
People often assume that a goal is scored only if it's hit directly by a player’s stick, forgetting that deflections off players' bodies are valid as well—this confusion arises because ice hockey referees must be vigilant to distinguish between legal and illegal scoring plays.
Mask: Goaltenders must wear an approved mask or helmet-and-cage combination at all times during play.; Leg Pads: Goaltender leg pads must not exceed 11 inches (28 cm) in width when worn on the leg. Maximum height is 38 inches.; Blocker and Trapper: The blocker (stick-hand glove) and trapper (catc...
Why people argue about this
People often assume that goaltender sticks are just wider for aesthetic reasons, but in reality, it's designed to provide better control on the ice by distributing weight more evenly across a larger surface area of blade, enhancing their ability to manipulate pucks quickly and accurately despite their smaller stature compared to skaters.
Contact with a goaltender in the crease is strictly regulated. A goal may be disallowed if an attacking player initiates contact with the goaltender in the crease or interferes with the goaltender's ability to move freely.
Why people argue about this
People often assume that just touching a goaltender in their crease is automatically penalized, but the real issue is when an attacking player initiates contact or hinders the goalie's movement freely – it’s about intent and obstruction, not just physical contact itself.
A player may not direct the puck to a teammate using their hand in any zone. In the defensive zone, a player may bat the puck along the ice with an open hand, but the puck must be touched by another player before a goal can be scored.
Why people argue about this
People often assume that a hand pass is strictly forbidden in all zones, leading to arguments when they see players using their hands to control the puck near the goal line in the defensive zone. The confusion arises because the rule allows for a "batting" action with an open hand in the defensive zone, but only if another player touches it first, not allowing direct hand-to-hand transfers.
Icing occurs when a team shoots the puck from their side of the center red line across the opposing team's goal line without the puck being touched. When icing is called, the face-off is held in the offending team's defensive zone, and that team is not permitted to make a line change.
Why people argue about this
People often think icing is only called when a player shoots from way out of bounds, but in reality, it's about timing - if the puck crosses without being touched by an opposing player within 30 seconds after leaving their defensive zone, it counts as icing regardless of distance. The confusion arises because they miss the nuance that timing and not just distance is crucial for calling icing.
Players may be substituted freely during stoppages of play and during continuous play ("on the fly"), provided the player leaving the ice is within five feet of their bench and is not actively involved in play. A team that has too many players on the ice is assessed a bench minor penalty.
Why people argue about this
People often assume that a line change is only about swapping forwards for defensemen, forgetting that it's also used to make substitutions during play. The actual confusion lies in thinking you can substitute freely whenever you want, which isn't true; there are specific conditions and limitations like needing the player within five feet of their bench.
Center Red Line: Divides the ice surface into two equal halves. Used for determining icing violations.; Blue Lines: Two blue lines are located 75 feet from each end of the rink, dividing the ice into three zones: the attacking zone, the neutral zone, and the defending zone. Blue lines are used fo...
Why people argue about this
People often assume that the goal frame height of 4 feet (1. 22 m) is a standard in ice hockey, but actually it's a very specific measurement set by league rules to ensure safety and fairness, with no universal precedent or common understanding outside of NHL regulations.
Major penalties are assessed for more severe infractions and require the penalized player to serve the full five minutes regardless of goals scored. Fighting results in an automatic major penalty for both participants.
Why people argue about this
People often assume that major penalties only apply to fighting incidents, forgetting that they can be called for a wide range of serious infractions like slashing or elbowing with intent. The confusion arises because the severity of these penalties is not always immediately apparent from just hearing the term "major penalty.
The penalized player serves two minutes in the penalty box, and their team plays shorthanded. If the opposing team scores during the power play, the penalty expires.
Why people argue about this
People often think that if a minor penalty is called for high-sticking resulting in blood, it's automatically 5 minutes instead of just 2. But actually, the rule specifies only 2 minutes as per NHL guidelines, even when there’s visible injury like bleeding.
A misconduct penalty removes the player from the ice for 10 minutes but does not result in a power play — a substitute player serves the coinciding minor or major penalty if applicable. Misconduct penalties are assessed for repeated minor infractions, unsportsmanlike conduct, or abuse of officials.
Why people argue about this
People often think that a misconduct penalty in ice hockey means the player is ejected from the game for 10 minutes, but actually, they're just removed from the ice without being replaced by an opponent's player and don't result in a power play. They misunderstand that it doesn't remove the team from scoring opportunities due to the absence of their player.
Off-ice officials include the official scorer, game timekeeper, penalty timekeeper, goal judges, video goal judge, and the NHL Situation Room in Toronto, which has the authority to review goals, potential missed stoppages, and other game-changing plays via video review.
Why people argue about this
People often assume that off-ice officials only handle paperwork and timekeeping, forgetting their crucial role in reviewing goal validity and game decisions through video review, which can significantly impact game outcomes. They underestimate how these roles intertwine with on-ice officiating to ensure fair play.
A play is offside when an attacking player precedes the puck into the attacking zone (crosses the blue line before the puck). The resulting face-off takes place at the nearest neutral zone face-off spot.
Why people argue about this
People often assume that offside is about players entering the zone before the puck, which isn't entirely accurate. They forget that it's actually about a player preceding the puck into the zone, regardless of when they enter – as long as they're there before the puck arrives, and if an attacking player does so, it results in a face-off.
Referees (2): Two referees oversee each game. They are responsible for calling penalties, awarding goals, and managing all aspects of game conduct. Referees wear orange armbands to distinguish them from linesmen.; Linesmen (2): Two linesmen are responsible for calling offside and icing violations...
Why people argue about this
People often assume that only the on-ice officials make decisions during a game, forgetting about the crucial off-ice roles like the official scorer and the Situation Room in Toronto, which can overturn calls based on video review. This oversight leads to misunderstandings because they believe all critical decisions are made by players and referees on the ice alone.
A penalty shot is awarded when a player on a clear breakaway is illegally impeded or when certain specific infractions occur (such as a defending player other than the goaltender deliberately falling on the puck in the crease). During a penalty sh...
Why people argue about this
People often think that penalty shots are only awarded for intentional fouls like tripping or slashing, forgetting that they can also be given for accidental infractions like a defender falling on the puck in the crease by mistake. They overlook how incidental contact during a breakaway can result in a penalty shot if it unfairly stops an opposing player's momentum and scoring chance.
The NHL Department of Player Safety reviews all incidents involving potential supplementary discipline. The department has the authority to issue fines and suspensions for dangerous play, whether or not a penalty was called during the game.
Why people argue about this
People often assume that just getting a helmet certified by any testing organization is enough for player safety, forgetting that it must be HECC-certified and properly fitted according to league standards. This oversight leads to misunderstandings about what constitutes adequate protection under NHL rules.
Each team has a designated players' bench on the same side of the ice, separated by a distance sufficient to prevent interaction between opposing teams. Penalty boxes are on the opposite side of the ice from the players' benches.
Why people argue about this
People often assume that players from opposing teams can mingle freely at their respective benches due to the separation distance, which they mistakenly believe allows for friendly interactions or even trades of equipment between benches. Actually, the rule is designed to prevent such exchanges and ensure no physical contact occurs between players from different teams while on their benches.
The top three teams in each division qualify for the playoffs, along with two wild card teams from each conference (the next two highest point totals regardless of division). Sixteen teams qualify for the Stanley Cup Playoffs, which consist of four rounds of best-of-seven series.
Why people argue about this
People often think that only division leaders qualify for playoffs, forgetting about those two wild card spots from each conference based on overall points, leading to debates over which teams deserve these wildcard slots.
The official NHL puck is made of vulcanized rubber, is one inch (1") thick, three inches (3") in diameter, and weighs between five and one-half ounces (5.5 oz) and six ounces (6 oz). Pucks are frozen before each game to reduce bouncing and provide a more consistent playing surface.
Why people argue about this
People often assume that the NHL puck's vulcanized rubber composition is a modern invention exclusive to ice hockey, forgetting its roots in other sports where similar materials have been used for decades. The confusion arises because they overlook the fact that vulcanized rubber has been utilized in various sporting contexts long before it became associated with ice hockey pucks.
NHL games are played on an ice surface measuring 200 feet (61 m) in length and 85 feet (26 m) in width. The corners of the rink are rounded with a uniform radius of 28 feet.
Why people argue about this
People often assume that the ice surface is perfectly square, forgetting about the rounded corners defined by a 28-foot radius, leading to misunderstandings about the actual playable area of an NHL rink.
Each NHL team is permitted to dress a maximum of 20 players for a regular season game (18 skaters and 2 goaltenders). During play, each team has six players on the ice: typically one goaltender, two defensemen, and three forwards (a center and two wingers).
Why people argue about this
People often assume that a team can dress 20 players for every game, which leads them to misunderstand how many skaters are actually on the ice during play. The confusion arises because they don't realize that only six players (one goaltender and four other positions) are active at any given time, even though their dressing room roster can be larger.
An NHL regular season game consists of three 20-minute periods of play with two intermissions of 18 minutes each. Each team plays 82 regular season games (the final season at this number before the planned expansion to 84 games beginning in 2026-27).
Why people argue about this
People often assume that each 20-minute period in an NHL game is a continuous flow without breaks, which leads to misunderstandings about how intermissions fit into the overall game structure. The confusion arises because they overlook the fact that these periods are divided by two 18-minute breaks, making up the full 66 minutes of gameplay per period.
A goal counts as one point for the scoring team. The player who shoots or last touches the puck before it enters the net is credited with the goal.
Why people argue about this
People often assume that credit for a goal goes solely to the player who shoots the puck into the net, forgetting that it could be another teammate's pass or even an opposing player's deflection that finally scores. The confusion arises because they overlook how the rule states the last touch before entering the net earns the point, not necessarily the initial shot.
Assessed when a minor penalty infraction results in an injury to the opposing player (most commonly high-sticking that draws blood). The penalized player serves four minutes.
Why people argue about this
People often think that if a player is penalized for high-sticking resulting in blood, it means they're automatically out of the game for the entire match. But actually, the penalty only lasts four minutes and doesn't disqualify them from play entirely. The confusion arises because the severity of the infraction seems to warrant more severe consequences.
The NHL operates under a comprehensive concussion protocol developed in conjunction with the NHLPA. Any player suspected of sustaining a concussion is removed from play and evaluated by a team physician in a quiet room.
Why people argue about this
People often assume that if a player is removed for suspicion of concussion, they're just resting on the bench until the game ends. But actually, the rule mandates a more thorough evaluation in a quiet room by medical professionals to ensure no lasting damage from the hit. This nuanced detail can lead to misunderstandings about when and how long players are truly out of action.
Helmet: All players must wear an approved helmet with a chin strap properly fastened. Players who entered the league after June 1, 2013 must also wear a visor. Full face shields are not required for skaters but are permitted.; Gloves: Padded gloves must be worn by all players. Gloves must not be ...
Why people argue about this
People often assume that helmets are only for protection in ice hockey, so they argue why skaters need to wear them when it's just a safety measure meant to prevent head injuries from collisions or accidental falls on hard surfaces. The confusion arises because some players might not fully grasp the rule’s primary purpose as a safeguard rather than an aesthetic requirement.
In the regular season, teams earn points in the standings as follows: Win (regulation, overtime, or shootout): 2 points; Overtime/Shootout Loss: 1 point; Regulation Loss: 0 points
Why people argue about this
People often think that standings points are solely based on wins and losses, but actually they're calculated by adding up goals scored (goals for) plus three times the number of goals against minus two-thirds of the goals scored against. This means a team can rack up more points through sheer scoring ability rather than just winning games.
Players' sticks must be made of wood, composite materials, or a combination thereof. The blade of the stick must not exceed 12.5 inches in length or 3 inches in width.
Why people argue about this
People often assume that NHL sticks can only be made of wood due to historical reasons, but in reality, the official rule allows for composite materials as long as they meet the blade length limit. The confusion arises because many players and fans are unaware of this material flexibility while still adhering to the 12-inch blade size restriction.
Each NHL team is permitted to dress a maximum of 20 players for a regular season game (18 skaters and 2 goaltenders). During play, each team has six players on the ice: typically one goaltender, two defensemen, and three forwards (a center and two wingers).
Why people argue about this
People often assume that a team can dress up to 20 players just in case they need backups for injuries, forgetting that only six are allowed on the ice at any one time. The confusion arises because this rule is about what teams can have available before a game starts, not how many substitutes they can bring onto the ice during play.
Each goal frame is 4 feet (1.22 m) high and 6 feet (1.83 m) wide, positioned at the center of the goal line. The goal frame is equipped with a net to catch pucks that enter the goal.
Why people argue about this
People often assume that the height of 4 feet (1. 22 m) for the goal frame means it's a low bar, but actually, the lower part is just the backboard, and the actual goal line itself runs from top to bottom across the entire width, making it taller than most people realize.
The official NHL puck is made of vulcanized rubber, is one inch (1") thick, three inches (3") in diameter, and weighs between five and one-half ounces (5.5 oz) and six ounces (6 oz). Pucks are frozen before each game to reduce bouncing and provide a more consistent playing surface.
Why people argue about this
People often assume that the puck's exact measurements are arbitrary or don't matter much since it flies through the air so quickly, but in reality, these precise dimensions ensure consistent performance from game to game, affecting how players handle and control the puck. Misunderstandings arise because they overlook how slight variations in size could drastically change its behavior on ice.
NHL games are played on an ice surface measuring 200 feet (61 m) in length and 85 feet (26 m) in width. The corners of the rink are rounded with a uniform radius of 28 feet.
Why people argue about this
People often assume that the rounded corners of the ice rink are meant for player safety, thinking they prevent players from accidentally colliding with each other at sharp angles. However, the actual reason is to ensure all shots on goal have an even chance of hitting the net, as the radius prevents any corner shooting advantage.
If two or more teams are tied in points at the end of the regular season, the following tiebreakers are applied in order: Regulation wins (ROW is no longer used; regulation wins take precedence); Regulation and overtime wins (excludes shootout wins); Total wins (includes shootout wins)
Why people argue about this
People often assume that if two teams are tied in points at season's end, they automatically go into a shootout to decide who gets first place, which is incorrect. Actually, the NHL uses more complex tiebreaking procedures like goal differential and even-strength goals against for those scenarios, not just a shootout.
