Ya Calderon, Derozan, Bosh, Johnson and Wright look like they are trying out there on defence. I haven't seen anyone light up Turk yet either, I've been kinda impressed with his defence actually. I think it's his length that makes up for his lack of foot speed.
Bargnani however is brutal. It starts with his defensive rebounding. 1 shot per posession for the opponent is the way to play defence.
