1. Muhammad Ali
The greatest boxer ever to step into a ring, you have to wonder what his last couple of fights did to his health. Ali endured classic wars and took incredible punishment against the likes of Joe Frazier and George Foreman. Meanwhile, he had three years on the sidelines after refusing to go to Vietnam. But this could have contributed to him staying in the sport longer than he should have.
We all know about his sad battle with Parkinson’s Disease. He absorbed a lot of damage before his last few fights, but unfortunate matchups against Larry Holmes and Trevor Berbick only stung fans’ hearts. This twentieth-century icon definitely stayed around too long. Legendary Boxers often struggle to resist the lure of the ring, the fame, and the glory. ‘The Greatest’ was no exception.
