What an exciting list you put together there. Key thing here: they've all "had their moments" in the national spotlight. It's nearly impossible to maintain it outside of a legitimate conference. Sure, there can be exceptions i.e. UConn, but for the most part, it's tough. It's so rare in today's era. Even you have to realize that when you started thinking of those schools.
Most of my list has been in the final 4 or elite 8 within the last decade, so I'd say the list is pretty good.....and I didn't even include Butler or Xavier. You on the other hand, came up with a completely obscure list of teams to make your argument, so we can certainly take a vote on who's list was more exciting.
