While I think Fedor would win I don't think Randy would get steamrolled. Randy's got the best match prep out of anybody right now. His game plan against Sylvia was pure perfection. Gonzaga, a much, much bigger opponent, was made to look like a little child. I think a fight between Randy and Fedor would go to the third round.
As for Fedor and the UFC, the thing with Fedor is he wants all his cronies to be signed to contracts too. Dana, the dick that he is, at least knows a good fighter when he sees one. Most of Fedor's buddies are nothing more than bottom feeding, low card fighters. Aleks, his brother, is somewhat decent I suppose, but having to sign on a bunch of crappy Russian fighters just to get one or two fights out of Fedor for huge money isn't something Dana wants to do. Of course, there's now word that Fedor is leaving M-1 (at least we got to see that sweet Hong Man Choi fight! Whoo!) so who knows where he'll go. DREAM? He made his name in front of the Japanese fans so Pride 2.0, aka DREAM, could be a possibility. Hopefully he can work something out with the UFC and we can see the best heavyweight in the world fight in the cage. Hell, he's already beaten Nog a couple times.
