Was it unprofessional? Yeah, absolutely but Chael's become an international celebrity because of his unprofessionalism. I honestly don't think what Silva did was any worse than what guys like Wanderlei Silva and Jon Jones have done.
That being said, as much as I don't like Chael Sonnen, I dislike Silva more. I'm sick and tired of seeing Anderson Silva wearing that belt and I want to see him get his ass kicked even worse than last time, I can live with Chael Sonnen being the Middleweight Champion so long as Silva is embarrassed and disgraced.
It's a shame we won't be able to see Silva fail and disappoint his family and friends and thousands of Brazilians in his home country.
