Look... I get you like to live in a fantasy land where firefighters n plumbers are “best fighters in the world”, but the reality is the real athletes are simply not choosing mma as career path n are instead make millions playing in nfl/nba. That’s the reason why those said firefighters n plumbers can look “impressive” fighting other d level athletes. If ever someone like lebron James decided to give mma a try it wouldn’t even be competitive. His superior athleticism would simply be too much for your average ufc “toughman contestant” to overcome with “skills” He’ll simply be too fast, too strong, too big n too good for your ufc average joe.
