Renzo Gracie is a legend in mixed martial arts and perhaps one of the most respected members of the community. Gracie has been a big part of helping Chris Weidman prepare for UFC 162, and when asked about Anderson Silva, had some choices words about the champion:
Gracie tells The Fight Network (video here) it's because Silva does not respect his opponents.
"Anderson is a guy that rubs many people the wrong way. He's not a humble guy. Even though he may speak humbly when he talks, when he's in the ring he doesn't act humble. He puts down his opponents. He acts in a way that again, we always know what is right and wrong, and by looking at that, we know it's wrong. It's like you can beat your opponent, but do it with respect."
