The most unpredictable division in MMA has always been heavyweight. That’s just how it goes when abnormally large, powerful, athletic men step inside a cage to punch each other in the face. The lights can go out at any moment.

It’s the reason why current champion Stipie Miocic holds the UFC record for most heavyweight title defenses at a whopping three. That tells you all you need to know about the unpredictability at heavyweight and how difficult it is to stay at the top of the mountain.

But that’s not to say there’s a shortage of all-time great heavyweights. It’s just that, when looking at the division’s history, there seems to be two names in the conversation for greatest ever: Miocic (18-2 MMA, 12-2 UFC) and former PRIDE champion Fedor Emelianenko (36-5 MMA, 0-1 BMMA).

Emelianenko has further opportunity to stake his claim when he begins his journey for Bellator’s title against Frank Mir on Saturday in a heavyweight grand prix quarterfinal to headline Bellator 198.

There’s also what could’ve been with former UFC champion Cain Velasquez, whose injury history has marred his career. But Velasquez (14-2 MMA, 12-2 UFC) is expected to return soon and who knows? Maybe he thrusts himself back into the conversation.
