Ali has Parkisons so no.
I don't think anyone has a shot now at beating Mayweather at 147lbs. I think Pacquiao during his first ventures in 147lbs and Paul Williams some 5 years ago had a good chance at beating Mayweather but the fights didn't happen and both are done now.
Unless Mayweather goes up a weight division i don't see many giving him problems, though Canelo will be a tough fight.
WHAT!!! The condition he's in now he can't even knock out a ****!
Dude you're ******* retarded, Ali has Parkinson's disease idiot. And he's old. Dumbass.
My sources say no.
Come out of retirement to take on Floyd mayweather?
