I didn't say pierce wasn't tough, obviously he is stronger mentally and physically than me or most every person on the planet but he does act like he got really hurt on fouls and try to milk calls more than most NBA players. I do give him credit he does not seem to flop a ton to try and draw charges, most of his "Acting" occurs on the offensive end trying to draw fouls.
For example, in game 5 he got fouled, fell, and clutched his knee and grimaced for more than a couple of seconds while on the ground only to get up and play the rest of the game limp free. I don't doubt that he felt pain in that situation but it seemed he tried to act more hurt than he was to try and get a flagrant called or something but if I remember correctly there was no way it was a flagrant. I wouldn't mind if he did it on fouls were a flagrant could be called but it seems like he is going down "the boy who cried wolf" route
I'm still a big Pierce fan but this is something he does that I don't care for
