He was the hardest fight I had.\u201d Nate continued, \u201cHe fought my brother two, three rounds, and they were just (expletive) squabbing. That\u2019s another guy in the category, too, and I knew fighting him that he was the man. He fought my bro, he was mad that Nick beat him, so he probably wanted to beat my (expletive) all over the place.\u201d Nate also explained why Neer was such a difficult challenge for him.

I was like, \u2018These fools are getting easier and easier.\u2019 I was like, \u2018This guy is probably a white belt. He\u2019s not even ranked in jiu-jitsu.\u2019 And back then, I was trying to get a black belt, so I knew. " "I was like, \u2018Man, this guy isn\u2019t even ranked \u2013 he\u2019s going to be hard and crazy, but at least he\u2019s probably just a white belt.\u2019 I fought him and he was the hardest fight I had. Those black belts were easy compared to him." Neer has had 53 professional MMA bouts in his career. He's beaten the likes of Anthony Smith, Duane Ludwig, Din Thomas, and more.
