CP3 didn't deserve to be in the discussion. Lots of steals and good defense aren't the same thing. The same could be said about Wade, for that matter.
I didn't like KG on the team at first, but then I thought about it. Look at the Celtics' defensive stats with him in the lineup, and then look at them with him out. It's pretty obvious how good he is, and how much we miss him on defense.
