Credentials: Won the UFC heavyweight championship in just his fourth career fight and just his third inside the Octagon, defeated the likes of Heath Herring, Randy Couture, Frank Mir, and Shane Carwin, participated in what was arguably the greatest comeback of all time, was easily the biggest draw in the history of North American mixed martial arts (MMA).
In a chat with MMA Junkie, his good friend and WWE manager and mouthpiece Paul Heyman makes the argument for him:
"Of course he is [a UFC Hall of Famer]. Listen, here's the thing: Look at the three that he lost to, number one. Number two, what if Brock Lesnar did what everyone else did and said, 'Feed me a guy every other month for three years so I'll get six victories a year. I'll be 18-0 before you put me in there with a Frank Mir, a former UFC heavyweight champion, or Randy Couture and the legends of legends in UFC.' ... Five and three? But look at the five - and look at the three."
In the interest of fairness, it should be noted that Lesnar had four wins under the UFC banner, not five. That said, the rest of Heyman's argument stands.
