Because the calls against the Mavs so heavily outweighed the calls against the Heat. Also, how many Heat players were suspended from the game?
First, the Mavs take more jump shots than the Heat. That results in less fouls, because most fouls are called when a player drives to the basket.
Second, a flagrant foul almost always (if not always) results in a one game suspension.
Did you want them to change the rules to fabvor the Mavericks?
Fact is, the Heat were hungrier, tougher and had more guts.
The Mavs, a more talented team top to bottom, blew it, and have no one to blame but themselves.
Crybabies and whiners blame it on the referees, as though they caused Nowitzki to have ZERO field goals in the 4th quarter of last nights game.
