Greatness is too difficult to define as we all have opinions on fighters that vary from fan to fan!

For Instance...

Ali is considered a Great and is adored by most of the boxing fraternity,not only for his boxing ability,but for his personality and the public persona he portrayed..

Where as..

All I see is a racist,draft dodging fucker that shit on Frazier when he was the only one who put out a hand to help him and stabbed him in his back....I see a Great Boxer,but a Cunt of a man!

Its all in your're own perspective!
