How many people have fought both Brock Lesnar and Fedor Emelianenko? Heath Herring has, and with the knowledge of competing against both fighters, he weighed in on the potential match up.

Herring spoke with Shambala Sports Radio on FiveKnuckles.com recently about how a battle between the two heavyweight stars might go down.

"Brock is much larger than Fedor, he weighs a lot more than him," Herring said. "He's a big wrestler - that's what he does - he comes forward, he tries to take his opponent down and control them.

"Fedor has really come along a lot in the last couple years with his stand up and the striking game. He's always pretty dangerous off his back."

Herring lost a decision to Lesnar in August 2008, while his fight with Emelianenko, which ended via TKO (doctor's stoppage), took place in November 2002. But, regardless of how much the top-ranked heavyweights have improved since then, Herring said that there would be other factors at play in a potential match up as well.

"If they got into it with each other, a lot of it would depend on the referee, depend on which organization that they fight in. I think that that really would be the key.

"If Fedor was able to land shots on Brock early on and catch him, he could take the fight. But on the flip side of that, if Brock was able to take him down, and they have a referee that isn't going to stand the fight up, you could see Brock getting the takedown and just holding him down and beating out a decision victory."

While the "The Texas Crazy Horse" was willing to give an extensive breakdown of the possible mega-fight, he would not go as far as giving a definitive prediction.

"Which way would I go?" he said. "I don't know, I'd give it about 50-50."
