Hardy is very lucky he is a popular former fighter, or I believe Dana White would have fired him.
First of all, confronting the ref after the fight is pointless. The fight is over, whatever infraction that so angered Hardy has happened. The ref is not going to go back and reaward the fighter a point if one was taken. The fight is over and nothing will change whether you confront the ref or not.
In other words, it's unnecessary drama that does nothing to Dana White but piss him off, and you cannot blame the guy when you consider the monumental amount of things he has to handle on a daily basis.
So he makes it crystal clear, forget about what anyone else did, if you work for me, and Dana stresses this to say not the ESPN guys, not the PPV guys, the guys that work for me, if you confront a ref again during an event, you will be fired. On the spot. Dana White frequently may threaten to fire soneone, but very rarely does he say on the spot.
Hardy let his emotions get the best of him and if Dana wanted to fire him, he would have been fired by now. But make no mistake, this was Dana White laying the pimp hand on Dan Hardy.
So as the fight game as goes life, how you handle yourself in adversity proves your worth as champion and you heart as a man. How does Dan Hardy handle his commentating duties going forward? What happens the next time he strongly disagrees with a referee?
One reason why a guy like Jon Anik is priceless. Never offends anyone, smooth MC of the event, able to interview any fighter with zero controversy, and is familiar to everyone.
