The trolling aside... watch the video on this kid. Like 1980 pointed out the hudl in the first post is actually from his sophomore season. He's looks to be a very instinctive cover guy (several times he read the QB and came off his man to make a play on the ball) who is physical for his size (albeit against high school level competition) both in press man coverage and run support. Maybe the injury halfway through his junior season scared some schools away from offering but he looks like a legit D1 cover corner in that limited bit of video. As far as pure coverage skills he looks better to me than Terrell Hall did in his hudl and Hall seems to be the much more highly touted of the two (although he doesn't seem to be pegged into the CB role like Coleman is).
