Prime Fedor would take him down and submit him in my opinion.
Title says it all. Not too sure about big Nog though. I think he would have wrecked cro cop in a more dominant fashion
Who knows it was different Era but I do know this thread will turn into shit real soon. It's going to turn into bashers discrediting Fedors career and his opponents.
Ricardo Arona, Randleman, and Coleman would all be able to wreck Cain, no need to even mention cro cop and nog.
Rofl.
You live in Narnia my friend. The only guy who was able to take him down was Cain and that was for a short period of time. Fedor is not a good wreslter and he would never be able to take him down, much less submit him.
