I definitely should have remembered the Ewing championship, my bad, and that is a demonstration of why you shouldn't rely on AI summaries for your searches!
But near as I can tell, The Big O went to a couple of Final Fours but didn't win a title (that is what wikipedia tells me). That is a CC parallel right there. Combine that with a guy who put up mind-boggling stats, was famously a little TOO interested in his stat line, and who was known as a bit of a difficult teammate, and it lines up pretty good. I think CC and Oscar are/were difficult for different reasons (he was prickly, she is more self-obsessed), but I would imagine being teammates with either of them is challenging while still appreciating that both will make you and your team better.
