Not only Manu, but Parker flops and Oberto is one of the worst (seriously, please go count how many times Oberto fell while setting a screen/trying to get a rebound). Pretty much Duncan is only the guy who plays straight up out there for the Spurs.
Suns don't flop all over the court and if you read arguments ponky and I had earlier this year, she said that was one of the reasons she hated watching Nash play in Dallas because he never sold the calls!! Bell flops all the time, I'll admit, but Nash takes some strong charges in there and you guys forget that he's not that big a guy... I don't think he was plotting Horry's suspension by selling a call. Incredible.
