Diaw has a tendency to coast so he's hard to gauge... I am careful to proclaim him finished bc the man has looked the part and has had rennaissances... I do think he's too heavy at this point and not in his playoff shape. He's lately getting the ball picked and TO a lot in the post bc he's lost some agility against perimeter players, which he would just dominate b4, as he had a combinations of bulk/heaviness, craftiness and still quickness that was very tough to stop... He's still got his craftiness, but he's now more bulky and less quick.
Manu being out puts an additional burden on him, but he was already coasting b4 the Manu injury. In fact, KA having a few games at the 4, and playing relatively well has covered up Diaw's state of play. Even Rasual has gotten minutes at the 4. I hope for our sakes, Diaw gets on his playoff diet/regimen soon. KA, as much as I like him, is not ready to carry that torch, and Rasual as much as I like him too, is a very, very streaky shooter.
