I have never seen a player expecting to get fouled, not get fouled because he was expecting it and not trying to make a play. Quite the contrary, when everyone knows they are going to foul, they usually barely have touch them to get the call. The refs don’t want to encourage mugging the guy and causing injury when all you are trying to do is stop the clock.
The two Minnesota players were not even going for the ball, especially the guy closest to the basket. He was repeatedly shoving Duncan in the chest. The ref was not out of position, he was right in front of the play. How can a guy not travel if two guys are pushing on him? What a terrible call. How is the ref going to defend that call.
