I think in MMA even more so than boxing you can't draw alot of conclusions from one loss. I mean Chuck has beaten Overeem/Randleman/Ortiz/Belfort/Metzger/Couture/Sobral/Bustamante/Horn/Monson.
This is a pretty good list. Right now I think there are only two LHW in the world that I'd give a 50-50 chance of winnning. Arona and Silva. Rampage barely got by Lindland who just isn't in the same league as Chuck. I just don't think Quinton is at the same level he was before Silva beat him.
