Current situation (just my own opinion, I can't trust all of the brackets out there)...
Locks: 26
Houston, TCU, Creighton, Butler, Kentucky, West Virginia, Arizona, Clemson, Rhode Island, Tennessee, Virginia, Michigan State, Xavier, Villanova, Duke, Michigan, Auburn, Ohio State, Texas Tech, Wichita State, Kansas, Cincinnati, UNC, Gonzaga, Purdue, Florida
Automatic bids: 25 (I estimate that 7 of the 32 conference tourney championships will be won by a locked team)
Which leaves 17 spots available.
