The Des Moines Regional is basically a Big Ten mini tournament, but the other Regionals should be very interesting with different conference mixes.
Big Ten has 6 and Pac-12 has 3 of the remaining 16 teams in the tournament. There is a reason they get so many spots in the tournament, it is because they are the toughest conferences. West Coast Conference and Big XII (Twelve) have 2 each.
