nope. hed still batter all of them.
wake up and smell the coffee. three of them are barely mma fighters and the other one has no chin, no subs, and no cardio past round 2.
I'm as big of a Fedor fan as you can get, but realistically Fedor would get mauled by Cain/JDS pretty much every time they fought. He's retired for a reason, it happens to all great fighters/atheletes in every sport, you get to a point where you can't compete anymore at the highest level, right now Fedor would probably not even reach title contention much less beat everyone on that list.
Anywho, in terms of career greatness and history, epic fights and what they mean to the sport and the impact they have made, and in terms of dominance during their reign, Fedor is the best HW of all time easily. The closest person would be big Nog, and Fedor destroyed him twice.
