Thanks for the discussion all, just caught up. I would rank things this way, noting it's only personal and it could change year by year:
1. National title
2. Final Four
3. ACC regular season
4. ACCT
5. Brown
6. In-season tourneys
Just kidding on the last two, but first four are legit. One interesting thing I've found looking at March Madness is that teams that win ONLY the regular season conference title are more likely to make Final Fours than teams that ONLY win the conference title. Not surprisingly, teams that win both are the most likely of all, but if it's one or the other, the regular season is a better predictor of NCAAt success.
