From the rumors I'm hearing Fedor is done fighting. You can bash all you want but every fighter in professional MMA would probably tell you the same... that Fedor was the one of the best there ever was. For 10 years straight no one could touch him, and while he didn't fight many of the current top HW, he absolutely dominated some of the best fighters there were at the time. They all have to come to an end sometime.
MMA HW division is the most unstable division of any combat sport, the fact that he lasted 10 years ranked in top 3 in the world is pretty amazing in itself. Look at UFC hw's, UFC HW title is like a curse. Mir had it, got himself wrecked, Brock had it, got ill, then got wrecked by a fighter, Cain got it, git himself injured VERY badly. That shit is a jinx I swear....
