#2 Anderson Silva
Anderson Silva is probably the greatest mixed martial artist the world has ever seen.
It's a brave statement, but the Brazilian truly is one of a kind and the things that he could do in the octagon during his prime seemed unreal. Silva defended his championship on numerous occasions, however, his status as a fan favourite began to change starting in 2010.

During a fight with Demian Maia, Anderson spent the majority of the contest mocking Maia and pretty much making a fool out of everyone in attendance.
It was supposedly done because Maia had shown him a great lack of respect, but Anderson clearly wasn't thinking about the overall impact of his actions on the night.
Dana White was understandably furious, and Anderson continued down his heel path through a failed drugs test and with another show of over-confidence against Chris Weidman.
Back into the past now to another candidate for the title of "best ever".
