Nowitzki shouldn't get suspended, he obviously got angry and for a good reason, the game was close and well fought and they were unlucky in the end. Stackhouse fouled Shaq pretty bad and got suspended. It's not every day that you see a 6-6, 98.9 kg guard put a 7-1, 147.4 kg center on the floor. It was bad but i don't know if he should've got suspended.
