Bracketology: Saturday has high seeds and bursted bubbles on the line

The NCAA Tournament is just days away but the madness officially kicked off yesterday.

The Pac-12 Tournament semifinals both had absolutely wild endings, with a buzzer beating layup, seven point deficits disappearing in twenty seconds, game tying free throws with no time left and both games ending in overtime. The American Conference quarterfinal between Connecticut and Cincinnati, two teams on the NCAA Tournament fringe, went to four overtimes and included a 60-foot buzzer beating heave to prolong the game. Oklahoma's Buddy Hield, a National Player of the Year candidate, hit a half court game-winner to beat West Virginia in the Big 12 Tournament semifinal -- only for the shot to be waved off after replay showed he released the shot a millisecond too late. Michigan, who was not in our field this time yesterday, knocked off the Big Ten Tournament's number-one seed, Indiana, with a last second three pointer.

The madness has commenced and has left college basketball fans wondering: What's next?

Tonight, there could be an NCAA Tournament 1-seed on the line in the ACC Tournament final between the Virginia Cavaliers and North Carolina Tar Heels. A 2-seed could be decided between the Oregon Ducks and Utah Utes in the Pac-12 Tournament final. And several teams are fighting to keep their tournament hopes alive while others, already eliminated from their tournaments, wait with bated breath for Selection Sunday.

For now, this is how we see it:

LAST FOUR BYES: Texas Tech, Oregon State, Butler, Cincinnati

LAST FOUR IN: Connecticut, Monmouth, Michigan, St. Mary's

FIRST FOUR OUT: Vanderbilt, St. Bonaventure, Syracuse, Valparaiso

NEXT FOUR OUT: LSU, Florida, Davidson, Georgia

Arizona seems to firmly be a 5-seed heading into Selection Sunday. If Seton Hall is able to defeat Villanova in tonight's Big East Tournament Championship game, they could jump to the 5-line. In the event that that happens, Arizona could be the team to slip from the 5-line to a 6-seed. Beyond that, the Arizona Wildcats look pretty locked in.

Both Virginia and North Carolina could end up with 1-seeds when all is said and done but tonight's ACC Tournament Championship will go a long way toward who gets the South Region 1-seed. Especially if Michigan State is able to win the Big Ten Tournament. If the Spartans win today and tomorrow, they should get a 1-seed, leaving the loser of tonight's Cavaliers-Heels matchup as a 2.

Bracket Matrix averaged out 92 bracket projections and currently has Arizona as the third 5-seed in the NCAA bracket. Their projected number-one seeds are: The Kansas Jayhawks, Villanova Wildcats, Virginia Cavaliers and Michigan State Spartans.
