In college it would have been a routine call. Offensive foul. They favor the defensive guy more.
But I agree that it was a bad call. But you really have to go to slow motion to be sure. It was not an easy call to make. But hey "karma bitch". How many times has Dirk flopped against us in the last decade by throwing his arms up like he was fucking mugged. When in reality there was no foul? Can't feel too sorry for them.
