In rugby, the contact times between players are usually longer, as a more wrestling approach is required to bring players down, as momentum cannot always be relied upon particularly when the lines between the teams are consistently close, not allowing for significant momentum to be developed before meeting a defender. In rugby, rucks and mauls may develop following a tackle when multiple players from each team bind together to move the ball in play (on the ground or in-hand respectively). In Canadian football, equivalents to rucks and mauls are virtually non existent, as play stops when the ball carrier is stopped. This difference can be summed up in the idea that in Canadian football the objective is to bring the player to ground or to disrupt a pass to end the play, whereas in rugby the main objective is to stop the player from breaking the try line.
