Anderson Silva was refusing to fight Chael for a while.
He simply doesent care about guys he believes he can smash. He also refused to fight Okami saying it was pointless. Eventually they did tango and Okami got burned. The guy is and continues to believe he is the best fighter on the planet, and he continues to push for big name fights. You guys complain about guys like Mayweather not going after Pacquiao or other UFC champions dancing around with the idea (GSP). But Silva at the twilight of his career is inviting the bigger challenges. People want Big or Superfights, but Silva at 36 getting criticized for actually going for them is puzzling to me.
