Yeah, I've watched the play again and you can see on all the replays that there was absolutely no foul, Hinrich falls all by himself, even the announcers acknlowedged it (saying that the Bulls caught "a break"). Doc and the Celtics discussed the call but the refs didn't listen. I'm glad that Hinrich missed his free throws ("ball don't lie"

) because it could have been a huge difference at the end of the game if he had made that play, especially when you consider that the C's had a chance to increase their lead before halftime.
Still, and after having watched it again too, I'm amazed by the technical foul called on Perkins, he did nothing else than grabbing his shoulder in pain...
