^^^ You are just a hater and I can't take your opinions seriously.
Que?!? I love Boxing and have followed it massively all my life. Ali's done some very incredible things, going to jail and losing some of his best years due to principle is one of them. His boxing was top class, albeit over rated with the rose tinted glasses that people who never saw him box often attribute to sportsman they never saw are prone to do. He will always be a legend, but part of it comes from getting ill with Parkinsons and what he has achieved after his boxing career. His legend is also more down to his fights for equal rights, and his steadfast position about the Vietnam war.
Try watching some actual documentaries and reading some actual historical reports as to what Ali did to Frazier outside the ring. There's a reason Frazier never really forgave Ali (reportedly saying that when Ali lit the Olympic flame, "they should have thrown him in"). He was a great fighter with a lot of heart, but by no means perfect. For starters he pretty much led a lynch mob to Frazier's house and stood outside barracking him. He was funny, witty, smart and incisive. He was also manipulative and self-centered beyond belief. At a time when racial issues still reared their ugly head, Ali called Frazier "Uncle Tom" which is akin to telling him he was a white man's puppet. He caused Joe's kids to be bullied at school. This despite the fact that Frazier helped Ali when Ali couldn't make ends meet. He thought only about himself, and there are many reasons why Joe never really forgave him.
You have no idea what you're talking about and with no real knowledge of the subject, so I'm afraid I can't take your opinion seriously
Someone like Pacquaio has achieved at so many different weight divisions, united an entire nation behind him, and now finds himself in politics within his own country. Ali was never the greatest because people said he was, he was the greatest because he said he was
Haye, Ali, Mayweather etc... they all fought in the same circus that is boxing, and they have all played to the crowds to sell fights.
It's also true that Ali gets some bad press in America due to his conversion to Islam, but a lot of his nastier sides are glossed over these days.
Sugar Ray Robinson was a better fighter than Ali for starters
So if you're just talking about ability and not legacy as you suggested, that's worth baring in mind. I'd say Jesse Owens certainly deserves to be near the top of any list of greatest ever sportsmen. What he did, where he did it, and the time it was done - Remarkable.

Basically, your list is missing Michael Jordan which is fairly criminal in itself
