The state of you calling Mayweather a sissy, you're the type of person who also labels fighters ''bums''. If Floyd is a sissy I don't know what that makes 90%+ of fighters.
Sugar Robert Helenius used this in very successful fashion against Dillian Whyte. The only opponent Whyte has not managed to down since 2017.
The rope a dope is apart of lexicon of boxing. Ali may or may not have invented it but he made it known. Greats have used it since, Mayweather most notably.
Given how early referees stop fights these days it's probably not that effective and if it does work it will most likely lead to brain damage if done extensively.
Floyd is a sissy but not because of his profession. Floyd says a lot of phony garbage about legendary fighters to boost his own ego without causation. He only bags on Ali to try to make himself #1 but Ali was a man of the people and a great fighter. Plus, he only talks cash **** about black fighters for all the irony of black people defending him outside of his boxing resume like he is Malcolm X or something. I respect his hard work and his heart that he put into boxing, outside of that Floyd Mayweather Jr. acts like a punk ass, sissified, self hating maggot.
Ali was the one who made Rope a Dope well known. He had taken a lot of big punches before he knocked out Jorge in round 8. What a Ring IQ !
