Clemson
RB C.J. Spiller -- Spiller did not need to run a 40-yard dash after clocking 4.37 seconds at the NFL combine, but he once again showcased his athleticism and explosiveness. He had a 36-inch vertical jump, and a 10-foot-6 broad jump, displaying the versatility that has separated him from the rest of the running back class and made him a high-first-round pick.
