He did well in the WEC but he really went downhill once he got into the UFC. The fights getting a lot tougher probably didn't help either.
I don't know about that, you look at 11 of his last 12 fights and it's pretty crazy.
Alessio, Castillo, Grant, Guillard, Henderson, Johnson, Njokuani, Pettis, Tavares, Varner, Volkmann
going 5-6 against that field
isn't to bad.
