that brings up the massive difference in the sports themselves. Boxing was huge at the time and Ali was the biggest name, but how many of his fights were truly global events? Maybe a half a dozen? Jordan had exponentially more games, and even if you just count things like series clinching games, his comeback, finals games, dunk contests and olympics, he was out there for world wide consumption far more often. I think Jordan competes simply on the globally famous question. He may not be as popular or beloved or respected, but those are different questions. But the dude is quite famous.
