Josh Barnett- The only man that i believe stands a chance against Fedor. His only losses come from Nogueira, Cro Cop(3 times), and his only KO loss from Pedro Rizzo. Steroids or not i dont care what anyone says, hes still up there. Way up there.
Sergei Kharitonov- I believe that he is one of the most underrated fighters. Many have not heard of this excellent, well rounded fighter. Holding wins over Rizzo, Werdum, Overeem, and Ninja Rua, Sergei is one bad ass fighter. He pretty much had Aleksander Emelianenko until he challenged Aleks to hit him in the chin causing Sergei to fall and receive a brutal TKO from knee strikes. But the whole time Sergei did not give up and was actually disappointed with the stoppage. One tough motherfucker for sure. If Sergei stays in there and gets a couple more fights under his belt, I think he could become one of the best.
Mike Russow- A police officer from Chicago and somewhat new to the MMA scene. His only loss is from Sergei Kharitonov. He pretty much had sergei but got impatient and caught in an armbar. He holds a notable win over Roman Zentsov.
