Fedor Emelianenko
As long as Fedor Emelianenko has competed in Pride, MMA fans have wondered what the UFC heavyweight belt would look like around his waist. Whatever reasoning you want to believe, Emelianenko has never stepped foot in the Octagon.
Now it looks like his career will be on the line when he makes his next appearance against Dan Henderson. A win might finally allow us to see Emelianenko in the UFC, but it is extremely doubtful we'll ever see UFC gold around his waist.
