This article does an excellent job of explaining why Lopez is not the center we need on this team if we are trying to win now, why he struggles defensively the way he does, and what Avery must do to try and rectify the problem.

I love Lopez to death but the guy simply does not have the physical tools nor the instincts to be even average defensively.

He has the talent to be a top 5 C but i think his lack of good coaching will prevent him from ever reaching his potential. Avery is a great guy and a players coach but he is not a guy that can get Lopez to the level he needs to be.
