I loved him as a RB, but quickness was not his forte. He was very fast and very powerful and OK with side to side movement.
Jenkins was a scat back with speed and quickness and no power. He was listed at 170 and I don't believe he ever actually weighed that much.
I understand that most would consider Staley the best and when all is said and done I think he will still have the best year that any RB at BYU has ever had.
