The thing that Douglas has going for him now is that, Chandler protects the paint, but if he's the only guy doing the defensive work, that could raise his chances of getting hurt. He needs some help. Who else would? Shumpert? Melo? We might be better off with Douglas for that alone. Our offense might not be the most fluent, but not only would will we be a high scoring team, we'll have a good defensive center, so Douglas might be the better choice.
