Like I told @thecryptkeeper, Gaethje has always been overhyped.
He knew coming to the UFC would result in him losing and getting knocked out. He said so in an interview (here is the link if you want to read it).
He is a wrestler by nature but prefers to brawl, I don't understand why he doesn't use his all-American wrestling more often. Makes no sense.
Yeah his refusal to use his wrestling can only hold him back in the long term. At this level of the game you have to use every tool available to you in order to succeed.
Khabib would bring it out in him, that would be an interesting fight actually.
Yeah he has a total disregard for his brain cells, he's gonna end up like Chuck Liddell, slurring his words a lot. I actually enjoy watching wrestling if they can get in some decent ground and pound, I bet he's real good at it and chooses not to for whatever reason. We already know he's an absolute maniac standing up, so what else has he got to prove.
