10. Brock Lesnar
No matter what type of combat you’re referring to, Brock Lesnar is one of the baddest men on the planet. But, of course, that fact didn’t phase McGregor one bit. When discussing the idea of a potential foray into World Wrestling Entertainment this past August, McGregor stated: “I haven’t really thought about it. For the most part, those WWE guys are (expletive). To be honest, they’re messed up (expletive) if you ask me. Fair play to Brock, he got in a fight but at the end of the day he’s juiced up to the (expletive) eyeballs so how can I respect that?” As one would expect, Lesnar certainly wasn’t having it. In an interview prior to the WWE’s Summerslam event, Lesnar stated: “I take sh*ts bigger than that kid. I know you guys all play (expletive) video games and you live in this (expletive) false sense of reality and (expletive). I’m 290 (expletive) pounds, all right? This guy’s 145 pounds and that’s if he’s lucky and gets up and eats his (expletive) Wheaties.”
