For whatever reason , maybe you think they still had plenty left in the tank , unfinished business with a revenge fight, or maybe a one off just to see your favorite guy fight one last time .
Mines Ricardo Arona , he got out of it just as I was getting into mma , saw his last few fights and the guy obviously stays in incredible shape , he's coming up on 40 but a one off in a legends type fight would be sick ...
Disclaimer :I'm not condoning guys who are completely shot coming back to take more brain damage , just a fun thread .
