Welcome back to the expanded edition of Joe Lunardi's Rundown. Since the start of February, this series has featured tournament odds, an element that will take you deeper into Bracketology. Bracketology provides a snapshot of how the bracket looks on a specific day, but through the use of Lunardi's extensive database of previous seasons, tournament odds tell you how the bracket is likely to look come Selection Sunday.
The 2012-13 season is now officially unlike any other in recent memory. With less than two weeks to go in the regular season, only one team -- Indiana -- would be considered a "lock" No. 1 seed for the NCAA tournament. To call the rest of the top line "wide open" is an understatement. Never before have so many teams had such a realistic chance to get there, making the upcoming conference tournament season far more meaningful than usual (at least at the top of the bracket).
So I'll be looking for two things as we head toward Selection Sunday: (1) Will the selection committee stay with the process long enough for the final conference championship games to matter? (2) How will this list narrow itself to avoid complete chaos with the final bracket? Since no one can answer the first question, let's take a look at the second.
Here's what I see evolving between now and the final verdict(s) on Sunday, March 17:
Barring a complete collapse, Indiana stays a No. 1 seed regardless of its play in the Big Ten tournament.
Duke and Miami determine a second No. 1 seed via their rematch this Saturday or, more likely, a potential "rubber game" for the ACC tournament championship.
ESPN Bracketologist Joe Lunardi provides an in-depth look at the latest bracket, detailing several scenarios for potential No. 1 seeds, and looking at four teams from smaller conferences that could earn at-large bids if they don't win their leagues.
