Not only is he the first to beat + submit Fedor , but he's also the only one who defeated them both. Years from now...he'll forever be remembered as that guy who submited the great one...no matter what happens next in his career...this is part of mma history , just like people still remember Buster Douglas' name only because he defeated Mike. I wonder if there'll ever be someone to defeat both Klitschkos ?...who knows
