I was at the Panthers game and watched him very closely. I went into the game as a Keon fan and left not a Keon fan. His body language was awful. His effort was awful. His production was awful. The guy is big and strong but plays small and weak. He's too slow and too lazy a route runner to separate. He gives up on catchable balls.
If he had any heart to fight through the defender and come back to the ball he'd have drawn a couple PI's for sure. He just flat gives up when the ball is in the air if it's not dropped right on him. You could just tell by the way he was carrying himself that he was completely disengaged.
I'm not an NFL coach but I coach youth football and just the way the guy carries himself would put him on my do not draft list. I don't know what happened or what went wrong, but its time to move on.
