Brock has never really been in a bout where he had to face resistance. He grew up bullying kids and loved it. Him skipping wwe for more training wouldn't have changed that , imo. That was his character. If he was bullied as a kid, maybe. I think lesnar is talented. I don't think lesnar enjoys the violence. He's not a Justin gaethje type. What Gaethje was saying about khabib , saying he doesn't like to fight, etc. That's more applicable to lesnar. This is a dude that is just a freak athlete and find some thing where he could use his talents. I don't think he's a natural fighter or have a love for martial arts. He has the love for money, competition, the adrenaline of winning but fighting and going through adversity of violence? Nah.
He's still a tough son of a bitch. But he's not built like those other guys. He can't be a nail and win. He has to be the hammer.
