What I liked:
He's obviously a very good athlete. Good speed, can swivel his hips around quickly and he's not afraid to hit. I also love his size. 6'4" for a cornerback is huge. A good corner that size can shut down just about anyone.

What I didn't like:
He's very raw at cornerback. It was his first year playing at corner, and it showed. He had a hard time in coverage and was holding and interfering on a lot of plays. He may have gotten away with it at the JUCO level, but he wasn't even being subtle about it and if he continues playing that way, he'll get flagged a lot at the FBS level.

My overall impression of Greene is that he's a bit of a project, but if he's teachable and can put it all together, he could end up being a pretty good cornerback.
