I just went out of my way to describe him NOT having to organize or have responsibilities. That's why you keep your two stable, traditional CBs in place. He's your Murdoch.David Luiz is a bit of a freak and can get away with more than the average player. Doesn't hurt that his hair confuses the opponent like a puffer fish.
Watch Callens with the ball on his right. He pretty much runs around it to get it on his left foot. That's contributed a few times to his lazy/late passes. I'd hate for him to be the one in the middle organizing when Chanot is clearly the vocal and organizational leader.
