Marquardt by TKO in the 2nd :)
I think Nate will win, but Chael has done pretty good , hes lost maybe once in 6-7 fights
Not just mentally, Nate should feel Everything stronger than Sonnen. Chael is not near his level..
I'm thinking Nate is more focused on Silva than he is on Sonnen. He really needs to watch it or he'll blow his chance at having his ass handed to him by Silva again.
