Alan Ameche. Thats all he did. He passed up Alan Ameche, and became the first NFL running back to have 3x 100 yard games in his first 3 games, and more yardage in his first 3 than Alan did. And for the nay sayers, this was NOT all he did. He had a 150, 112, 96, and a couple in the 80s the rest of the way after coming back from his injury.
Oh, and he came back from two major knee injuries. What else do you want from the man? He is running like he did back here, back when he was a rookie.
