Wow! Risky Fight for Fedor. Overeem is largely unknown to mainstreem MMA fans. Yet, Overeem is Fedors most dangerous opponent yet! If Fedor loses, he lost to an obscure fighter and tarnishes his reputation further. If he wins, no big deal, mainstream won't notice..... Over WHO? Man he has a lot to lose on this fight. He's going to need this win or bye bye reputation.
