They aren't in the same vein at all.
I don't think Shaq wasted hardly any talent, actually; he WAS overweight but he actually used it to his advantage a la Barkley many times. I only mentioned him because of other posters bringing him up.. in reality, he wasted very little. I don't agree with some of how the arguments against him are being gauged, either. For example, being bad at FTs isn't necessarily proof of a waste of talent - many people have confirmed Shaq practiced the out of FTs through his career.
VC consciously, selfishly did not try his hardest in Toronoto and likely, in other points of his career.. his athleticism was unmatched, and he could've contended for the GOAT IMHO, but he CHOSE not to take advantage. Extremely mentally weak. You've completely ignored this aspect by comparing the two.
