Well it's pretty clear Anderson Silva isn't going to lose until he gets too old. I'm going to go out on a limb and declare him the greatest champion in UFC history. Not only is he the longest reigning champion with the most title defences, he makes trained, championship calibre fighters, look like chumps. Who's the last person who lost, respectfully, to Silva?
I'd say Chael Sonnen (UFC 117)
I was going to say Sonnen, but it turned out he was on PED's, so fuck him.
UFC Rio was good except for 2 things.
1- Every American looked like a bum out there
2- Silva vs Okami was fixed. Okami took a dive , watch the replay and Silva reactions
There is rumours that Schaub and Griffin took dives that night as well.
Not that I believe that bs. All 3 of those guys got beat by better opponents.
