I don't know how much stock you can put into d-league defensive rotations, particularly when most players on the floor are not doing job... which is pretty much the norm in that league, and there's really poor communication. I'll say this, he does need to become more disciplined defensively, that much is certain.
But what else do we have to go on as far as any defensive improvement he has made over the past year?
We'll see, I think both Walker/Giddens will get there shot this year.
