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.

The 2024/25 NCAA basketball season is down to its 10 final days of competition, with conference tournament seeding hanging in the balance as top teams try to build up some March Madness momentum.

Proving that nothing is guaranteed, two teams suffered upset losses on Thursday night.

In the ACC, No. 11 Duke fell to unranked Louisville 70-62. Though senior guard Jayda Curry led both the Cardinals and the game with 24 points, Louisville's victory came largely from the free throw line, where the Cards snagged 22 points but the Blue Devils only banked four.

The Big Ten followed suit, when unranked Indiana downed No. 8 Ohio State 71-61. Fueled by double-digit performances from four different Hoosiers, Indiana took an early lead and never relented, outshooting and out-rebounding the Buckeyes to hand them their fourth loss on the season.

NCAA conference titles take center court in decisive weekend matchups

While some teams are stumbling at the finish line, others have a shot at clinching conference hardware this weekend.

With a two-win lead on the ACC table, No. 1 Notre Dame has the chance to lock down the conference's regular-season title on Sunday, when the Irish will take on second-place No. 13 NC State.

The consequential clash has earned Raleigh a visit from ESPN’s College Gameday, with the pre-game show slated to build upon last weekend’s success in South Carolina with another high-stakes matchup.

Meanwhile in the SEC, No. 7 LSU’s season is also on the line. Unlike the Irish, however, the Tigers are simply trying to keep their dwindling conference title hopes alive, facing a must-win game against No. 14 Kentucky on Sunday.

To claim the SEC’s No. 1 seed, LSU would also need both No. 2 Texas and No. 6 South Carolina to stumble in their regular-season home stretch.

Beyond conference titles, the regular season’s wind-down can provide insights into how far teams can run into the postseason, as any upsets this week could spell busted brackets — or unexpected surges — come March.
