burnside rulesとは 意味・読み方・使い方

The Burnside rules were a set of rules that transformed Canadian football from a rugby-style game to the gridiron-style game it has remained ever since. Named after Thrift Burnside, captain of the University of Toronto football team (although he did not originate them-- see below), and first adopted by the Ontario Rugby Football Union in 1903, the rules introduced sweeping changes to the way football was played. The rules included:

• the reduction to 12 players per side from the standard 15
• the "snap-back" system in which the ball was heeled backward from the line of scrimmage by the center
• the requirement for a team to make ten yards in three successive downs or lose possession of the ball
• the reduction to six men from the previous eight allowed on the line of scrimmage when the ball was put into play.
