15. Sean O’Malley vs. Kris Moutinho
Nobody knew who Kris Moutinho was before he stepped up to fight Sean O’Malley at UFC 264. In the end, he suffered a brutal beating at the hands of “Sugar.” His toughness was amazing but arguably he showed too much heart for his good. His coaches failed to protect him and may have harmed his long-term health.
Moutinho absorbed 230 significant strikes against O’Malley while landing just 70 of his won. He came forward like a zombie but O’Malley overmatched him. This was a strange fight to watch because fans saw his brain cells depleting before their eyes (via MMA Junkie).
