1 mayo 2011 año - Safety Rule change

Descripción:

Changes were made regarding kickoffs to limit injuries. First, kickoffs will be moved from the 30 to the 35-yard line, repealing a 1994 rule change. In addition, players on the kickoff coverage team cannot line up more than 5 yards behind the kickoff line, minimizing running starts and thus reducing the speed of collisions.
