This is not really an over-reaction but I don't know if he'll ever be an elite corner due to his lack of size. He's going to have a tough time with bigger WR and screen plays for the rest of his career. The guy is giving up a lot size. I just don't see him being more then a All-ACC performer on defense. Right now, Harris looks like a better corner to me and personally I think the OU game would have been a lot closer if Reid sat on defense in favor of Harris. I was at the game sitting in the endzone but it look Greg had a tough time getting off the WR block.
On offense the sky is the limit. He is always one touch away from six and rarely makes a negative play. We could design an offense around him with screens and toss. I don't know how well he can run patterns but with ability to cut there is no reason why could be special as a slot receiver. On offense, the guy could be a Heisman candidate if he can learn to run patterns and is able to run the ball inside and outside. He lacks size to get off the press but his speed may discourage most corners from pressing him.
