Football injuries

Anyone here know how the amount of injuries for different positions in football based on NCAA or NFL statistics?

Based on the current RPI statistics, the breast-stroker has a 37% chance of an ACL tear over an entire season. Also, the discus thrower has a 12% chance of hitting himself in the head with the discus over a lifetime of throwing. Finallly, a golfer has a 2% chance of tripping on a mole tunnel and absorbing major head trauma. Hope this helps.

really 2% huh? maybe we should all wear helmets on the course
