Well other peopled mentioned how he still has hand trouble, but that shit still stays in your mind, and makes you think about how it risks your career everytime you throw hard. Plus the power needed to take top level guys out is what fucks up his hands, not hitting bags. And yeah Ali backed his shit up which is why people loved him, although they hated him at first from being all brash and cocky. People always wanted to see the cocky black champ lose. Floyd does his cocky shit for attention because people will never love him due to his style. My point is he does the same talking as Ali, but because he only boxes and doesn't brawl people don't like him. But its still an act to get noticed. Ali is considered the greatest for his out of ring shit as much as his in ring shit. If Floyd just kept his mouth shut boxing circle guys might like him more but I guarantee you most people would still have no idea who Floyd Mayweather is.
