After 1000s of sprints in his lifetime, By the time the ball is snapped and put in his belly if there was a hole and if Boobee seen green? He would have blown straight through it fresh as a daisy. Sure he may be a bit winded at the end of the last play but elite athletes like him have extra and can do it. They work out that way. Blast, Blast, Blast, Blast. (Not so awesome the next day) Bo Jackson could do 30 rushing attempts per game over and over and over pounding dragging people, hard yards.. Week in, week out.
