Stolen from CBS draft analysis:
Positives: Smooth and fluid, can flip hips and change directions without losing speed, and looks natural in his backpedal. Provides tight man coverage without giving up a lot of separation. Durable three-year starter improved every year. Did a decent job against top competition, most recently against A.J. Green of Georgia. Effective in both man and zone schemes. Gives good effort against the run. Smart in the classroom - top intangibles.
Negatives: Thin build, can be easily blocked by receivers. Will have to get stronger to be effective in the NFL against the run. Didn't play a lot of "press man" coverage, likely because he doesn't hold up well to contact. While fluid and athletic, is not overly fast and may lack the true "sixth gear" speed for NFL man coverage assignments without deep help. Ball skills are decent but nothing special.
