Common elements
The long snapper snaps the football directly to the punter, who then drops and kicks it before it hits the ground. There is usually never a holder on kickoffs, because the ball is kicked off a tee; however, a holder may be used in certain situations, such as if wind is preventing the ball from remaining upright on the tee. The long snapper’s job is to snap the football to the holder, who will catch and place it on the ground for the kicker. Turnovers include interceptions (a defender catching a forward pass intended for the offense) and forced fumbles (taking possession of the ball from the ball-carrier). The role of the defense is to prevent the offense from scoring by tackling the ball carrier or by forcing turnovers.

The most common types of injuries are strains (sprains), bruises, fractures, dislocations, and concussions. The chain crew system has been used for over 100 years and is considered an accurate measure of distance, rarely subject to criticism from either side. A typical chain crew will have at least three people—two members of the chain crew will hold either of the two sticks, while a third will hold the down marker. The chains (consisting of two large sticks with a 10-yard-long chain between them), are used to measure for a first down. Each carries a weighted yellow flag that is thrown to the ground to signal that a foul has been called. Once the ball has been kicked from a scrimmage kick, it can be advanced by the kicking team only if it is caught or recovered behind the line of scrimmage.
