Who cares about Mazzagatti. More often than not he does a fine job. The real concern should be the judges like Lyoto pointed out.
The problem with Maz is he doesn't understand the rules of a sport he is reffing. If a fighter is winning when they commit a foul that causes the fight to be stopped. The fight is ruled a NC. If you are losing and you commit a foul then its a DQ. In the Jones vs Hamill fight when /Jones was destroying Hamill but he still got DQed because of the elbows.
