Sport Science: Sylvester Williams (3:18)

Sylvester Williams visits the Sport Science lab to test his skills in advance of the NFL draft. (3:18)

North Carolina defensive tackle Sylvester Williams is considered a candidate to be drafted by any of the three NFC North teams choosing between Nos. 20-26 in Thursday night's first round. This Sport Science video helps explain why.

Williams derives his power from 33-inch thighs, larger than at least a few of your waists. (Sadly, not your friendly blogger's.) In the video, Williams demonstrates his quickness in the form of a 10-yard split that was faster than the average result of this year's running back class.
