That wasn't it as far as trash talk is concerned. Mayweather also took the opportunity to make a formal claim as the greatest boxer to ever enter the ring, singling out the late boxing legend Muhammad Ali for why he doesn't deserve the number one slot:

"Is Ali the same fighter that got beat by a guy with 7 fights? Leon Spinks beat Muhammad Ali when he only had 7 fights…If we really tell the truth, what's the heavyweight guy that Ali fought 3 times? Ken Norton really beat Ali all 3 times. Go back and look at the fights."

Primary Income Streams & Multi-Million Contracts

Mayweather went onto admit that Ali was "a pioneer" for refusing to fight in the Vietnam war and giving up his titles as a result. But then he said he would have done the same in that situation:

"And I would have done the same thing if I was in that era. He did what he was supposed to do in that era."

Whether Mayweather is truly the greatest boxer of all time or not, he is undoubtedly the most expensive, and he doesn't seem interested in lowering his rates any time soon.
