Well I think he's in a tough division seeing as his best aspect of MMA is Jiu Jitsu, you have guys like Maia and Palhares in the division already who I think would both beat Thales Leites.
He is going to struggle also against guys with good standup and decent takedown defence, as Thales standup is mediocre.
I agree with JT42, Marquardt would eat him in a rematch, those point deductions are annoying, but fair from what I remember. So Nate can't complain, it's just a shame when a fighter loses in that way.
Fedor fights I want to see..
Fedor vs. Josh Barnett
Fedor vs. Randy Couture
Fedor vs. Tim Sylvia -
Fedor vs. Andrei Arlovski -
hmmmmm, i wonder how many become reality..
