2. Aaron Donald - Defensive Tackle - Pittsburgh
Aaron Donald, like Dri Archer is very small for his position. He measured at just 6'1" 285lbs, but every other measurable was nearly comparable to Jadaveon Clowney, and was the best performing DT at the combine.
While defensive ends are coveted for speed and agility to pressure the quarterback, Donald measured among the elite defensive ends in these categories. He was fifth among all defensive lineman in the 40-yard-dash at 4.68 seconds, which is an enviable number for an early round defensive end. He was also fourth among all defensive lineman in the three cone drill, a measure of agility in tight spaces. An elite score for a defensive end is a about a seven second time. Donald posted a 7.11.
It isn't just speed though, Donald showed explosive upper body power leading all defensive tackles with 35 bench press reps and lower body power with a 9'8" broad jump, again leading all defensive tackles.
Because of his general lack of bulk and elite athleticism expect a team to use him in different ways, as an interior lineman in a four-man front, and moving outside in a three-man front.
