Anderson doesn't draw as much money as you think, one look at PPV buys will tell you that.
Second of all, this is two men locked in a steel cage and Anderson can punch him, kick him, knee him, elbow him, and has tons of different ways he can administer punishment to Chael, not a kindergarten class where one guy has to go to time out because he was a potty mouth.
And third and finally, trash talking has always been a part of Combat Sports, people need to realize the UFC has to sell these fights and that fighting is fifty percent promotion, fifty percent performance. There's a reason Floyd Mayweather is the king of PPV and it's because he knows how to promote fights.
THE PERFECT STORM
THE PERFECT RECORD
THE PERFECT FIGHTER
