had Cockrell projected as a third or fourth round draft choice. He was described as agile, consistent, aware, with good anticipation and a good feel for the game. The main issues that worried scouts were physical attributes like having small hands, a skinny lower body, thin frame, short arms, and his lack of strength during press coverage and taking on blocks. He attended the NFL combine in Indianapolis and was able to perform all the drills well. Although he had a good showing at the combine, Cockrell decided to participate in all the events during Duke's Pro Day. He was able to improve on all of his combine numbers, including a sub-4.40 in the 40-yard dash, 12 bench presses of 225 lbs, and a 39-inch vertical.
