Bracketology: Top seedings, bracket watch and more

For most leagues across the country, the regular season is over and conference tournaments are set to begin later this week. The final sprint to Selection Sunday on Nov. 30 (6 p.m. ET, ESPN) has arrived.

There are 31 automatic bids with 33 at-large teams chosen by the NCAA volleyball committee. Volleyball seeds the top eight teams in each region, and the top four in each region serve as first- and second-round hosts. The rest of the bracket is filled out to balance it competitively and geographically. The highest-remaining seeds also host the regionals, and the 2025 Final Four is in Kansas City, Missouri, on Dec. 18 with the finals on Dec. 21.

Bracket watch

The ACC does not hold a postseason tournament. The regular season, which concludes Nov. 29, decides the automatic bid to the NCAA. A tournament doesn't seem necessary with the level of excitement the conference has already provided with more to come in the final two weekends. Last Friday Stanford and Pittsburgh had perhaps the match of the year that the Cardinal won 16-14 in the final set. Louisville pulled a reverse sweep on Miami on Sunday, while SMU took down Stanford in four sets. Six teams are within two games of the top spot and five of those teams sit inside the top-16 of this week's Bracketology. Louisville, Pittsburgh and Stanford lead the ACC at 14-2 and the Cardinals still have to play the Panthers and Stanford in the final two weeks. Not only will those games decide the ACC champion but will go a long way to deciding the No. 2 seeds and possibly the final No. 1 seed for the NCAA tournament.

Bubble watch

Oregon makes the jump into the field with the biggest win of any bubble team, beating Purdue on Saturday. UCF fell out of the field with a loss to Cincinnati, but with matches against Arizona State, Kansas State and Kansas still to come, the Knights fate is in its hands. The same can be said for Michigan State, which still has Penn State, USC and UCLA on the schedule. With a win in one of those matches, the Spartans are likely in. Missouri and Oklahoma, sitting on the wrong side of the bubble right now, have the SEC tournament starting Friday. A good showing, perhaps with an upset -- Oklahoma would meet Kentucky in the quarterfinals, Missouri is set up to meet Texas in the quarters -- will be necessary for an at-large bid.

Last Four In: Georgia Tech, Michigan State, South Florida, Oregon

First Four Out: Missouri, Oklahoma, Cincinnati, Florida State

Next Four Out: Georgia, Central Florida, Tulsa, Pepperdine
