Mayweather an Ali

Many people on this forum hate PBF for his antics. For dancing around and calling himself the best fighter in the world and being an overall cocky son of a bitch. But wouldn't you say that the same thing that Floyd is doing now, Ali did in his own time? Where do you think Ali came up with the name "the greatest". He got in everyones face and stirred up the crowed. Saying his opponents were amatuers compared to him. Floyd does generally the same thing except he adds the fact that he's rich to the matter.
