My Take
Okay, Mighty Mouse is one of those fighters who quietly made me rethink what "greatest of all time" even means. At 5-foot-3 he had no business being that dominant, but Demetrious Johnson turned the UFC flyweight division into his personal chess match, stacking up eleven straight title defenses like it was routine. What I love is that he wasn't a trash-talking, highlight-chasing showman, he just outthought everybody, and then occasionally did something absurd like that suplex-into-armbar that still lives in my head. He fights like a problem-solver, all timing and angles and patience, and you can tell the brain is always two moves ahead of the hands. Add in the wholesome gamer-dad energy outside the cage and he's basically the anti-hype superstar. I have nothing but respect for the guy.
