Just to reference the original question - how good are any other conferences?
The Big East to me looks like a great UConn, a frisky Marquette and Creighton, and then... very very average.
B1G is basically Purdue and a bunch of really meh and really bad teams. And all of them, including Purdue, have big flaws.
SEC looks good on paper, but Bama plays no defense, Tennessee has Rick Barnes, and Auburn is Auburn. I could see their next level down teams surprise though - SC, UK, FL.
Pac12 is Arizona, Wazzu, average Oregon, and then its pretty bad pretty fast.
I think the SEC is the only other conference where half the league isn't hot wet garbage.
It would be a good year to have say six or seven Big12 teams in the S16, but its always so random you can't count on anything.
Could also mean a year where the mid-majors shine, but outside of SDSU (who was better last year) and St. Mary’s (who is good but isn’t “Gonzaga at its peak” good), who would that be? There aren’t any mid-majors this year that are screaming “look at me” yet… then again, did anyone see FAU coming last year?
