Bracketology locks: Which teams are already in? Who has work to do this week?

The 2024-25 college basketball season was the first in which the NCAA officially incorporated Wins Above Bubble into the selection process for the NCAA Tournament. It’s a results-based metric that allows for the comparison of teams that played vastly different schedules, and it is closely correlated with selection into the field of 68.

A year ago, the 40s in WAB proved to be the chopping block for at-large consideration. West Virginia was the best team left out with a No. 43 WAB ranking, and Xavier was the worst team to get in with a No. 49 WAB ranking.

Miami (Ohio) suffered its first loss in the MAC Tournament quarterfinals on Thursday but remains a “lock” in CBS Sports Bracketology heading into Selection Sunday because its WAB ranking is 37th. With a WAB score of 1.70, the RedHawks are recognized for having nearly two more wins against their schedule than the average bubble team would.

Every team in the top 40 of WAB is considered a lock for our purposes entering Friday’s action, except for any team that could still slip out of the top 40 based on conference tournament performance. The only team fitting that bill is Saint Louis, which enters the day at No. 39 in WAB as it prepares to open Atlantic 10 Tournament action against George Washington. A loss would drop the Billikens into the 40s, leaving them as a non-lock entering Selection Sunday.

Here is a look at 39-50 in WAB entering Friday’s action:

Against that backdrop, here are the teams we are comfortable calling locks to make the 2026 NCAA Tournament. Other categories include the “almost there,” “on the bubble” and “longshot” tiers.

ACC

Locks: Duke, Virginia, Louisville, North Carolina, Miami, ClemsonAlmost there: NC StateBubble: SMULongshot: Virginia Tech, Stanford, Cal

NC State really is “almost there.” The odds of the Wolfpack getting left out when the bubble is so mushy feel slim. The only hesitation stems from how flimsy their resume is upon a close inspection. Their best road wins over Clemson and SMU depreciated in value, and a 24-point beatdown of North Carolina comes with an asterisk since UNC was missing stars Caleb Wilson and Henri Veesaar. A tally of 11 Quad 1/2 victories is great, but there are zero victories against teams ranked in the top 30 of the NET. By comparison, Auburn has four such victories, and Texas has three (including a head-to-head win over NC State). A side-by-side “scrub” of the Wolfpack against those teams in the committee room might go poorly.

Atlantic 10

Lock: Saint LouisBubble: VCU

Saint Louis reached lock status by knocking off George Washington 88-81 in the quarterfinals of the Atlantic 10 Tournament on Friday. The Billikens trailed by 21 and would have dropped into the 40s of Wins Above Bubble — also known as the danger zone — with a loss. The Billikens were probably fine already. Now? They should have nothing to worry about, even if they don’t win the A10 Tournament.

Big 12

Locks: Arizona, Houston, Iowa State, Texas Tech, Kansas, BYU, TCU, UCF

The Big 12 Tournament proved inconsequential for the NCAA Tournament bubble. Longshot hopefuls like Oklahoma State, West Virginia and Cincinnati all wilted early. UCF achieved lock status by knocking out the Bearcats before losing to Arizona in the quarterfinals. It would be a shocker if these eight teams don’t comprise the conference’s dancing contingent when the bracket is revealed.

Big East

Locks: UConn, St. John’s, VillanovaLongshot: Seton Hall

Seton Hall’s at-large aspirations were bleak entering Friday. But they were extinguished in a 78-68 loss to St. John’s in the Big East Tournament semifinals. Though the Pirates have 21 wins, they have just one victory over a projected at-large team (NC State), and they will arrive at Selection Sunday well outside the top 50 in the all-important WAB. This was a great defensive team that merely lacked the offensive firepower to break through for needle-moving wins.

Big Ten

Locks: Michigan, Michigan State, Illinois, Purdue, Nebraska, Wisconsin, Ohio State, UCLA, IowaLongshot: Indiana

Because Indiana still averages around 40th nationally in predictive metrics, the Hoosiers are not being pronounced dead yet. But any case for IU would be flimsy since the Hoosiers are not a top-50 team in results-based metrics, which are more closely tied to selection. There is some resemblance to last year’s Xavier team that barely snuck into the field, but even that comparison is a reach for an IU team that has dropped six of its last seven games. The bubble is bad, but it’s not bad enough for Indiana to be legitimately considered.

MAC

Lock: Miami (Ohio)Bid thief candidates: Akron or Toledo

The MAC is on track to produce a bid thief after Miami suffered its first loss of the season against UMass in the quarterfinals of the league Tournament on Thursday. Miami completed the regular season unbeaten and is on track to arrive at Selection Sunday with a Wins Above Bubble (WAB) score of nearly 2.0, which will likely put them in the top 40 of that vital resume metric. The beauty of WAB is that it allows the committee to compare the achievements of teams that have played vastly different schedules, which is useful since Miami did not play a single Quad 1 game. 

Mountain West

Lock: Utah StateBubble: New Mexico, San Diego State

New Mexico and San Diego State will have at least some chance of at-large consideration if they reach the Mountain West Tournament title game. They play each other on Friday night for a spot in the championship. But there is no scenario where either becomes a “lock” outside of winning the tournament.

SEC

Locks: Florida, Alabama, Vanderbilt, Arkansas, Tennessee, Georgia, Kentucky,  Texas A&MAlmost there: MissouriBubble: Texas, Oklahoma, Auburn

Oklahoma came agonizingly close to reaching “almost there” status on Friday by taking Arkansas down to the wire in the SEC Tournament quarterfinals. Ultimately, the Sooners came up just short in an 82-79 loss. Reaching the semifinals was always the target for OU, and it came up one game short. This team played great basketball down the stretch, but at 19-15, the Sooners might be a tough sell in the committee room.

WCC

Locks: Gonzaga, Saint Mary’s, Santa Clara

The WCC appears destined to send three teams to the NCAA Tournament after Santa Clara crept from “almost there” to lock status on Thursday morning because of favorable results elsewhere on the bubble. Gonzaga won the WCC Tournament during its final year in the league, but Saint Mary’s and Santa Clara have clearly done enough to be at-large teams in a year where the bubble isn’t very good. There’s not even a question on the Gaels, but Santa Clara’s case was at least somewhat up for debate following its loss to the Zags in the WCC Tournament final. Ultimately, the Bulldogs will arrive at Selection Sunday as a a top-40 team across the board in the metrics used by the selection committee.
