Explaine what makes him not classy. I guess u have seen something I haven't.
Anybody can talk like they are humble before and after fights, but his actions inside the ring show his true character. It started with Damien Maia, a fellow Brazilian and true class act, and Silva just acted a complete cocky fool in the ring for 5 rounds and never finished him or took it seriously. It was sad for Damien to be treated like that by a countryman. I'm sure he would have rather been destroyed in short order by a classy competitor than be taunted for 25 minutes in front of his legion of fans.
In stark contrast, Chael Sonnen talks mad shit to hype up fights, but he is a classy fighter without losing any edge, and he is humble and gracious in defeat or victory. If you watched The Ultimate Fighter where Chael was a coach, you know that he is one of, if not the, best coach ever. He truly cared about his fighters and showed beyond any doubt that his ACT is just that, an act to sell tickets.
Anderson is one of the best fighters ever, but he just couldn't stop the success from making him a complete douchebag.
