Let's look at the main differences between the CFL and NFL.Field DimensionsThe CFL field is 110 yards compared to 100 in the NFL. The CFL field is also 12 yards wider than an NFL field. Field goal posts in the CFL are placed at the goal line as opposed to behind the endzone.The number of players allowed on the fieldAs the field is wider, the CFL allows 12 players on the field at a time. In the NFL, only 11 players are allowed on the field at a time. The 12th player on the field adds another eligible wide receiver for CFL offenses.The number of downsIn the NFL, teams have four downs to move the chains, but in the CFL, teams have only three. The CFL limits teams to three downs to make teams pass the ball more.Offensive players are allowed to motion at the time of the snapIn the NFL, one receiver may be in a lateral movement when the ball is snapped. The CFL allows many different kinds of motion pre-snap. Multiple offensive players can move in any direction, forward, backward, and laterally.Punt returners cannot fair catchIn the CFL, punt returners must return the football. There's no fair catch in the CFL and the returners get a five-yard halo to catch the ball. The NFL doesn't have a halo rule unless the returner calls for a fair catch.SinglesThis may be the most interesting difference between the CFL and NFL. If a CFL team cannot return the football out of the end zone because of a touchback, the kicking team is awarded one point. If a CFL team misses a field goal, the defensive team is awarded a single point.
