One big difference between the regular season and the postseason has been the play of Rasheed Wallace - in particular on defense.

Wallace makes his big presence felt - The Boston Globe

His 13 points yesterday were overshadowed by his tough defense on Dwight Howard. While Wallace no longer possesses the athleticism to tussle with Howard without fouling, he has the savvy to use those fouls wisely and the tricks to frustrate the Orlando strongman into mistakes. Howard was ready to lose his cool in the second half because Wallace served as a mental and physical menace. He trash-talked, used his hips to push Howard out of comfortable position, and when he fouled Howard hard as he rose for a dunk, Wallace shook his head to indicate there would be no easy baskets here.
