Comparison of American football and rugby league

A comparison of American football and rugby league football can be made because of their shared origins, resulting in similarities and shared concepts in terms of scoring and advancing the ball. Aside from Canadian football, rugby league is the sport most similar to American football. Both sports involve the concept of a limited number of 'tackles'/'downs', and in both sports scoring 'touchdowns'/'tries' takes a clear precedence over goal-kicking.

Generally, American football games last much longer than 80-minute rugby league matches. Because the field is reset after each tackle in American football, it is much slower paced than the more hectic rugby league, in which play stops for only as long as it takes the tackled player to get back to his feet and return the ball to play. Another major difference is that only the player with possession of the ball may be interfered with in rugby league. Defending players interfering with any other attacking player (and vice versa) will incur a penalty. Passing in the two sports also differs in that American football players are allowed to throw the ball forward (subject to some restrictions) whilst in rugby league forward passing is illegal unless the pass is performed with the foot and the receiver is behind the kicker when the ball is kicked.

Another obvious difference is the players' attire, with helmets, gloves and large amounts of padding around the body being the norm for American football. Comparatively little padding (if any) is used in rugby league, with a small fraction of players opting for light headgear as hard helmets are not allowed^[1]

The defense owns a major advantage in rugby - tackling is allowed but blocking is forbidden, making for a very bruising game.

Origins

British colonists and the British military in Canada brought rugby football to North America. It, along with association football, became popular in American and Canadian universities. At the time soccer and rugby were not as differentiated as they are now and teams would negotiate the rules before playing a game. The sports of American football and Canadian football evolved from these intercollegiate games.

Meanwhile in England a schism developed in rugby football between those who favoured strict amateurism and those who felt that players should be compensated for time taken off work to play rugby. In 1895 this resulted in the formation of a break-away sport, rugby league, the rules of the two codes of rugby (union and league) would themselves diverge.

The field

An American football field

A rugby league field

American football is played on a rectangular field 120 yards (110 metres) long by 53 1/3 yards (49 metres) wide. Near each end of the field is a goal line; they are 100 yards apart. A scoring area called an end zone extends 10 yards beyond each goal line. Yard lines cross the field every 5 yards, two rows of hash marks run parallel to the side lines near the middle of the field. At the back of each end zone, there are two goal posts that are 18.5 feet apart (24 feet in high school). The posts are connected by a crossbar 10 feet from the ground, and may be in the shape of the letter 'H' or the letter 'Y'.

A rugby league field is very similar, it is 120 metres (131 yards) long and about half that in width, there is a line across the field every ten metres. An in-goal area extends six to twelve metres beyond each goal-line. At the goal line are a set of goal posts in the shape of the letter 'H', used for other forms of point scoring: drop goal, penalty goal and conversion.

On some American football fields artificial turf is used for the playing surface, however rugby league is played exclusively on grass.

Players

See also American football positions, Rugby league positions

An American football team has 11 players on the field at a time. However, teams may substitute for any or all of their players, if time allows, during the break between plays. As a result, players have very specialized roles. Thus, teams are divided into three separate units: the offensive team, the defensive team and the special teams. While each team in the NFL has a 53-man roster, only 48 players can dress for a game.

In rugby league the same players have to both defend and attack. There are thirteen players and four replacements in a rugby league team, with only twelve interchanges of players allowed to be made throughout the game (ten in the Australian NRL). If the interchanges are used up and a player becomes injured and cannot continue, the team simply has to play a man short. Unlike American football, all players must attack and defend and there is no equivalent of special teams.

Broadly speaking, offensive and defensive linemen in American football correspond to forwards in rugby league and other players are somewhat similar to backs. Basically the job of the forwards in rugby league is to get the ball over the advantage line and give the backs space and a chance to be creative and move the ball around, which will hopefully result in points. However, rugby league players are far less specialised than American football players.

Many of the positions have similar names but in practice are very different. A fullback in American football is very different from a fullback in rugby league. However, some of the positions are fairly similar: for instance, the stand-off/five-eighth and halfback carry out a similar role to a quarterback in American football.

Advancing the ball

In American football, the team that's in possession of the ball (the offense) has four "downs", to advance the ball 10 yards towards the end zone. When the offense gains 10 yards, it gets another set of four downs. If the offense fails to gain 10 yards after 4 downs, it loses possession of the ball.

A down ends, and the ball becomes dead, after any of the following:

• The player with the ball is tackled.
• A forward pass goes out of bounds or touches the ground before it is caught. This is known as an incomplete pass. The ball is returned to the original "line of scrimmage" for the next down.
• The ball or the player with the ball goes out of bounds.
• The player either goes or is forced out of the field (out of bounds)
• A team scores.

This closely resembles the six-tackle rule in rugby league. The team in possession has a "set of six" tackles before having to hand over possession. A key difference is that there is no automatic way of earning a new set of tackles in rugby league. Each set is effectively a chance to score, with failure to do so resulting in relinquishing possession. Another major difference is that play stops briefly when the player in possession of the ball is tackled and resumes once he gets to his feet and returns the ball to play.

Players can advance the ball in two ways in American football:

• By running with the ball, also known as rushing. One ball-carrier can hand the ball to another; this is known as a handoff.
• By passing the ball forwards to a team-mate. This can only be performed once on a down, and cannot be done if the ball crosses the line of scrimmage.

In rugby league the ball cannot be passed forward, so players can advance the ball by either running with it, or kicking it ahead and chasing it. This concept is preserved in American football; any player may pass the ball backwards, regardless of player position and location of the field. In addition, a ball passed backwards remains live, even if not caught, so long as it remains in play, similar to rugby league.

Following a down, the ball is returned to play within a restricted time limit by a "snap" in American Football. All players line up facing each other at the line of scrimmage. One offensive player, the center, then passes (or "snaps") the ball back between his legs to a teammate, usually the quarterback and play commences.

In rugby league the ball is returned to play following a tackle via the "play the ball", in which the tackled player gets back to his feet and rolls the ball back to a teammate, usually the hooker. The tackled player will usually try to return to the ball to play as quickly as possible before the defensive line can re-form.

Possession may change in different ways in both games:-

1. An automatic handover takes place when the team in possession runs out of downs / tackles.
2. When the ball is kicked to the opposing team. This can be done at any time but it is normal to punt on the last down / tackle.
3. Following an unsuccessful kick at goal.
4. When an opposing player intercepts a pass.
5. In rugby league the opposition are awarded a scrum if the player in possession drops the ball forwards or makes the ball go forwards with any part of his body other than his feet. This is called a knock-on.
6. When the player in possession drops the ball and it is recovered by an opposition player. This is called a fumble in American football and a knock-on in rugby league.
7. In rugby league if the ball goes out of play, the opposition are awarded a scrum the "loose head and feed" of the scrum. Penalties and 40/20 kicks are exceptions to this rule.
8. In American football possession changes hands following a successful score and the team scoring kicks off to the opposition. In contrast, in rugby league the team who conceded the points must kick off to the team who scored. (In some amateur levels of American football, and in Canadian football, the team who conceded the points has the option of kicking off to the opposition rather than receiving the kickoff, but this option is extremely rarely invoked.)

In both codes, tactical kicking is an important aspect of play. However kicking in general play is more common in rugby league.

Passing

In American football, the offense can throw the ball forward once on a play from behind the line of scrimmage. The forward pass is a distinguishing feature of American and Canadian football as it is strictly forbidden in rugby league.

The ball can be thrown sideways or backwards without restriction in both games. In American football this is known as a lateral and is much less common than in rugby league.

In both codes, if the ball is caught by an opposition player this results in an interception and possession changes hands.

Tackles and blocks

See also tackle (football move)

In both games it is permitted to bring down the player in possession of the ball and prevent them making forward progress. Play then restarts from the next down or tackle. In rugby league, it is common for the player in possession to 'off-load' the ball, passing out of the tackle (before forward progress is halted) in order not to use up a tackle and to keep the play alive.

In American football, players are allowed to 'block' players without the ball, within certain restrictions. This is not permitted in rugby league and would be considered 'obstruction'. Players not in possession of the ball may not interfere with each other.

Scoring

A touchdown is the American football equivalent of rugby league's try. Ironically, a try requires the ball to be 'touched down' to the ground, whereas a touchdown doesn't. In American football it is sufficient for the player carrying the ball to cause the ball to enter the end zone (in-goal area) while still in bounds, by carrying it in or holding the ball in or through the imaginary plane of the goal line. In rugby league the ball must be pressed to the ground in the in-goal area. An American football touchdown scores 6 points and a rugby league try is worth 4 points.

In both games, following a try / touchdown, there is the opportunity to score additional points by kicking the ball between the posts and over the bar. In American football this is called an extra point or a "point after touchdown" (PAT) in the NFL (worth 1 point), in rugby league it is known as a conversion (worth 2 points). There are two key differences between an extra point and a conversion, conversions cannot be charged down like an extra point attempt but they must be taken from the same position as the try was scored. Hence it is important to score under the posts rather than in the corner, which makes for a difficult kick. Rugby league has no equivalent to American football's two-point conversion, in which the scoring team chooses not to kick at goal, but attempt a second touchdown from short range.

In American football teams often opt to go for a field goal (worth 3 points) rather than attempt a touchdown. The rugby league equivalent, also called a field goal, is worth only one point and is much less common. The key difference between a field goal in the two sports is that an American football field goal attempt is normally kicked with a team-mate holding the ball, whereas in rugby league the field goal is attempted using a drop-kick.

A similar concept in rugby league is the penalty goal. Following the award of the penalty, the attacking team may opt to kick for goal rather than advance the ball by hand or punting. This scores 2 points in league. The penalty goal is similar to a field goal in American football in that the ball is kicked from the ground and may be held by a team-mate (although almost never is), but it cannot be charged down. The nearest equivalent in American football is the rarely used fair catch kick.

American football has one further method of scoring which does not exist in rugby league. If a ball carrier is tackled in their own endzone (in-goal area) with the ball or steps out the back of the end zone with the ball, this results in a safety which scores 2 points. In rugby league this does not result in any points but causes the team in possession to kick the ball back to the opposition from under the posts.

Cross Code Matches

At least one cross-code match between American football and rugby league has been played. On August 1st, 2009 the Jacksonville Axemen of the AMNRL played the Jacksonville Knights of the Florida Football Alliance. The first half was played under American football rules, the second half was played under rugby league rules. The score at half-time was Jacksonville Axemen 6 - Jacksonville Knights 27. The final score was Jacksonville Axemen 38 - Jacksonville Knights 27.

Gridiron Rugby

A version of rugby league played on American football fields by teams of 11 (rather than 13) players is known as Gridiron Rugby. A professional league called the United Rugby League is planned for North Carolina and nearby states to begin in Spring 2013. [1] [2]
