I thought he was a big, deceptively fast runner (not elite speed, but rarely caught from behind once he hit the jets) with great vision (really set his blocks up well), patience, leg strength, and a nose for the end zone. He could also literally do it all (run, block, return kicks, block punts, catch passes etc.) and was fantastic on screen plays. Here's a link to some of his highlights - notice how well he sets up his blocks and how much room there is for him to run; he's often barely touched because of how good he is in space and how patient he is with the ball. Also great that everyone on that team could BLOCK!! Look at the WR's (Johnson and Johnson) mixing it up downfield on each and every run and MY GOD WHAT ABOUT PAUL JEFFERSON AND SEAN MCHUGH BARRELING OUT OF THE BACKFIELD AS A FBS??? They were hat on hat every time they lined up. That certainly helped.
