Here's my bracket for today. Florida State takes Iowa State's spot in the First Four. Northwestern remains in despite an overtime loss, mainly due to other teams's blunders. And, regions+ first round sites are here today!

2 Kansas, Baylor, Duke, Indiana
3 Georgetown, Ohio State, UNLV, Missouri
4 Gonzaga, Kansas State, Michigan, Connecticut

A quick note about seeding first. The seeds above are the "true seeds". Some teams have had their seeds switched below (e.x. Illinois and Vanderbilt) for bracketing purposes (no re-matches, keep teams in the same conference apart, etc.)
