This is one of the strange board memes that is very popular, despite having no basis in logic.
It is not true, at all, that the Cuse would have certainly "won that NC going away with AO." That is just a fun myth, something we like to pretend on this board, sort of like, Rautins being more valuable than Wes. The rest of the nation laughs at that sort of imaginative nonsense.
Rick beats AO by almost every measure of basketball efficiency, from the most basic, to the most advanced metrics. Rick was a better player, and he will get much more serious NBA looks than AO ever got: even before AO's injuries, pro scouts weren't interested.
Ricky was the real deal, but AO simply struck fans the right way, and so Ricky's been underrated. My guess is that AO is so beloved because he was the first effective Syracuse big man on offense since Otis Hill, so much like Nassib in football, AO gets the "we've been down so long" extra love, simply by being the first good offensive big man to come along in a decade. AO was no BE DEF POY: but AO was very good, and he did have soft hands and a spin move than kinda looked like Otis. Because the fanhood with AO is so intense, Ricky's greatness gets lost behind myths about AO's missing national championship.
