The one thing I give Ali that Mayweather doesn't have is charisma. Some guys can say anything and get away with it, Muhammad Ali was one of those men. I think he said a lot of mean things, and was arrogant, but there was smile in the corner of his mouth it was clearly a show. Mayweather is arrogant or whatnot, but it comes off as fake because you know deep down he is insecure, and just wants people to know how great he is. I find Mayweather's situation sad, while Ali made people loving acting that way.

IMO Ali would have worked in a team sport more than Mayweather who has the same personality as Terrell Owens.
