Hope beyond hope this guy leaves in the Summer. He's a disaster area who is never ever ever in the right place.
He can compete physically, and win individual challenges, but he doesn't know how to play football properly. He's needed someone to hold his hand his whole career, and could just about get by out at RB. At CB, and as captain, he's not good enough, and doesn't have a clue when ordering others about, he pulls other players out of position with his mad movements. He's a huge reason we're so easy to score against.
Okore/Lescott/Baker/Dunne/Collins would be better. Comparing him with Vlaar is ridiculous, they're on different planets. Ron is a defender, Micah is an athlete.
