The Power Four wrapped up their 2024/25 NCAA basketball seasons on Sunday, with newly minted conference tournament champions punching their tickets to the March Madness tournament.

While the Big 12's weekend was all chalk as No. 8 TCU added their first tournament title since 2005 to their 2024/25 regular-season conference trophy on Sunday, the ACC capped their contest with chaos.

No. 11 Duke put the conference — and the NCAA selection committee — on notice, upsetting both No. 6 Notre Dame and No. 7 NC State en route to their first ACC tournament championship in 12 years.

In the SEC, No. 5 South Carolina had the last word against No. 1 Texas. After splitting their two 2024/25 meetings and sharing the regular-season title, the defending national champion Gamecocks turned the SEC tournament final into a defensive masterclass, defeating the Longhorns 64-45 to claim the conference trophy.

Meanwhile, Sunday's Big Ten finale saw No. 4 UCLA enact revenge on their crosstown rivals, No. 2 USC. After dropping both their matchups and ceding the conference's regular-season title to the Trojans, the Bruins held USC to just 34.3% from the field and 28.6% from beyond the arc to snag the tournament crown with a 72-67 win.

Conference winners eye NCAA tournament seeding

With their Sunday wins and their automatic entries into the upcoming NCAA basketball tournament, conference champions are now eyeing their shots at top national seedings.

While TCU and Duke each made strong cases for increasing their seeds, UCLA and South Carolina fully cemented themselves as frontrunners to top the 2024/25 bracket.

"When you win this [SEC] tournament and play the schedule that we play, I do think we’re the No. 1 overall seed," remarked South Carolina head coach Dawn Staley. "There isn’t anybody in the country that has played the schedule that we have played, that had share of the regular-season title, won this tournament and beat the No. 1 team in the country."

The stats back up Staley's claims. South Carolina played more Top 25 opponents this season than any other currently ranked squad, winning 12 of those games — seven against Top 10 teams. The only three losses they logged all season came against No. 1 Texas, No. 3 UConn, and No. 4 UCLA, with the Gamecocks handing the Longhorns two defeats in return.

UCLA head coach Cori Close took a more diplomatic approach when asked about top seeding after winning the Big Ten title.

"I think it would mean a lot for us [and USC] both to be No. 1 seeds," Close told ESPN. "And I hope we do get the chance to do it [in the Final Four] in Tampa a fourth time."

The final decisions rest with the selection committee, who will reveal their 2024/25 NCAA tournament bracket this Sunday.

How to watch Monday's Big East tournament final

Though the Power Four have handed out their hardware, other DI conference tournaments will be in action all week, with the Big East championship tipping off Monday night.

No. 3 UConn is hunting their fifth straight Big East tournament trophy, but they'll have to beat No. 23 Creighton to hoist it.

The No. 1-seed Huskies and No. 2-seed Bluejays will tip off at 7 PM ET, with live coverag on FS1.

For the first time in 21 years, Texas basketball is the No. 1 team in the nation, with the AP Poll minting the Longhorns as the fourth top-ranked NCAA team of the season on Monday.

"I'm so happy for my kids, they’ve earned where they are today," Texas head coach Vic Schaefer told the AP ahead of his team’s resounding 57-26 win over unranked Georgia on Monday. "There's so much parity in the game right now."

The Longhorns’ leap comes after then-No. 1 Notre Dame’s double-overtime loss to NC State on Sunday, a result that sent the Irish falling to No. 3 in the rankings. The Wolfpack, on the other hand, earned one of the week's biggest boosts due to the marquee win, jumping four spots to No. 9.

After spending 12 weeks at No. 1 before now-No. 4 USC snapped a school-record 23-game unbeaten streak earlier this month, UCLA also benefitted from Notre Dame’s slip-up, rising one spot to sit at No. 2.

Along with reigning champion No. 6 South Carolina, who began the 2024/25 NCAA season as the No. 1 team, there have now been four squads atop this season's AP Polls. There have never been more than four to reach that summit in the survey’s history.

Small shifts litter Monday's AP Top 25

Similar to the minor changes in the Top 3, the Poll’s remaining 22 teams saw mostly incremental shifts as the final 2024/25 NCAA regular-season weekend looms.

ACC standouts No. 24 Florida State and No. 25 Louisville re-entered the rankings this week after snagging upset victories over then-No. 20 Georgia Tech and then-No. 11 Duke, respectively. As a result, the now-unranked Yellow Jackets joined Illinois in exiting this week's poll.

The Blue Devils saw the biggest drop after their loss to the Cardinals, falling five spots to No. 16, while last week's upset loss to unranked Indiana sent Ohio State down four spots this week to No. 12.
