Um, I feel like Emmitt was hurt plenty, the way I remember it. The fact that he was durable and played forever as a starting RB doesn't mean he was healthy that whole time. Hamstring issues and some issue with his heel. That Giants game when his shoulder was dislocated and he was basically playing with 1 arm.
And, I may be remembering wrong or confusing a couple of different games, but I think he had a game against the Vikings where he broke some big runs (like, to the point where people were buzzing that it might be a game where he'd challenge the single-game rushing record -- he had something like 150 yards before the 1st half even ended). But then he broke his hand when his finger got caught in a facemask stiff-arming a guy on his way into the endzone on the first of two TD runs in, like, a 30 second span. We got the ball back too quick after a turnover for them to realize his hand was broken yet before the next TD run. Then he got pulled from the game when they realized.
But, yeah, Emmitt got hurt a bunch.
