I have been pleasantly surprised with Keon. Most of what people said about him being slow etc. had my expectations lowered. But he has made plays this year that I believe show a lot of promise. He certainly has a lot to improve, but I believe they are fixable. When they show his releases in that Steve Smith video, it would seem to me he just needs to simplify it, make one move and go. With his size and strength he should be able to win at the LOS. They even say he is more quick than fast which I do not think is a knock for someone his size. His RAC ability is good.
Keon is someone we took for who he could be, not for who he is now, lets give him some time to get there.
