i had heard he had ran a 4.39 with his trainer from tigerdroppings but haven't found any aritcles yet.
I don't think either Toe or DD ran at the combine and I'm not sure about other parts of the workouts. Only 4 of the 16 running backs chose to run at the combine after getting prodded by their agents about the 'slow' track at the RCA Dome. Alot of the GMs were really pissed about the RBs not running the 40.
the combine is for players that declared for the nfl, if a underclassman declaired himself eligable for the draft then he would be at the combine. Its a chance for the draft eligable players to raise their stock with the nfl teams.
