Dude what. DC is literally Fedor's worst matchup at HW. A heavy wrestler who is hard to submit (unlike Coleman or Randleman) and would get on top and stay there. Fedor got outwrestled quite a bit by better TD guys, his fans usually claimed he allowed this to happen which is risable. Eg in the Arona fight it was supposedly his intention to get taken down constantly, mounted, and come as close to losing as mathematically possible (even before taking Volk Han's shenanigans into account).
Now imagine that fight but with a bigger, better wrestler, possibly with elbows (or at least with punches to the head allowed), and with unified rules style judges (though it'd be the same even in PRIDE criteria). If elbows are allowed a cut win would be an extremely significant threat too.
