There are obviously a lot of factors that play into an athlete being popular. Charisma, looks, and of course talent play huge roles. But there are also intangible things like defining moments...moments where you truly capture an audience with a performance. Ali, for all of his talent and charisma, had a flair for the dramatics. When you think of Ali there are so many special moments that come to mind. Aside from the politicized atmosphere of when he became known and his outspokenness....there are so many legendary moments inside the ring in his career: defeating Liston, Zaire and Foreman, his trilogy against Frazier, etc. He was tremendous talent but he also was able to rise to occasions and create lasting memories. He is a truly iconic figure. There are also fighters who are just "likable" to a large audience...like Oscar. He has a huge crossover appeal. But even in Oscar's case...he has been involved in BIG fights...obviously not on the scale of Ali...but he has created DRAMA with some of his fights...Quartey, Trinidad, Vargas, etc. So i disagree with people who think his appeal is mostly because women just find him sexy. The great athletes, the ones that are not only popular but will be remembered for a long time....ultimately have performed on the big stage. They have provided us with moments that are thrilling and memorable. Floyd, for all of his talent, has not done that. He has not fought anyone or been involved in fights that one can say "My gosh, that was memorable." Add to that...he just isn't a particularly likable guy. Ali was brash, but he would charm you...put a smile on your face. Floyd just comes across as arrogant. Whether the rest of his career will provide us with enough defining moments to change that...remains to be seen.
