N. Illinois QB cramps up or hurts his leg, then valiantly hops off the field on the other leg because he has respect for the game and doesn't want to be a little pussy... commentators call him stupid for not stopping the game to give backup QB time to warm up.
Guy should get props for having balls and not delaying the game unnecessarily like 94% of athletes do... if an athlete can get off the field safely without hurting himself, then that's what he should do.
