Degrading physical attributes due to inevitable aging, is generally the main reason for fighters losing their fights and being forced into retirement. Some believe that it’s the boxing abilities that abandon a fighter first, but in reality, technical ability is more than just muscle memory, over time it gets hardwired into one’s brain and forgetting it requires a very long period of inactivity.
Juan Manuel Marquez hasn’t displayed a decline of either physical or technical aptitude yet. Every one of his fights is not only competitive, but also consistently crown pleasing. His ability to box as well as brawl makes him a very unpredictable challenger. At the age of 40, his experience and participation in the fight game is legendary. As far as his late career goes, his loss to Floyd Mayweather Jr. is the only one that cannot be disputed or questions by the fans.
