This weekend's worst offenders (in no particular order):
Dirk Nowitzki - Game 4, third quarter. Hack across the forearm, somehow he lands on his backside, sliding across the court. You can do better Mr. MVP. here
Ginobili - He basically rips away a rebound from Stoudemire (in the backcourt), and then exagerrates the foul to the point where it looks like he got hit with a tire iron. If he wants to get hit with a tire iron, I suspect he could find plenty of volunteers.
Curt Thomas - This one is the winner for me. He tries to flop after he runs into a screen.... on a DEAD BALL. As in, there was already a call somewhere else, and he still tries to draw a foul.
(Update: we would be remiss if we didn't mention this gem of a deadball flop from last year, Baron Davis flopping against Okur here.)
