Reigning NCAA basketball champions UConn powered up this week, signing former Wisconsin standout Serah Williams out of the transfer portal — and beating both LSU and North Carolina to the punch.

After several top programs — including the Tigers and the Tar Heels — tried to court the All-Big Ten first team forward, the 6-foot-4 rising senior officially opted to play out her final year of eligibility with the Huskies on Wednesday.

Averaging 19.2 points and 9.8 rebounds per game last season, Williams joins a talented UConn frontcourt that includes starters Jana El Alfy and 2025 NCAA Freshman of the Year Sarah Strong.

2025/26 NCAA basketball rosters snap up top talent

With most big-name transfers now committed, next season's college basketball landscape is coming into view.

Despite missing out on Williams, LSU is likely this year's transfer portal winner, having signed Notre Dame freshman forward Kate Koval and highly touted South Carolina sophomore guard MiLaysia Fulwiley to the Tigers' 2025/26 roster.

Ohio State also made headlines on Wednesday, inking Florida forward Kylee Kitts — the younger sister of South Carolina standout junior Chloe Kitts — following the Buckeyes' loss of star junior Cotie McMahon to Ole Miss.

While the transfer portal window closed last week, there's no deadline for signing with a new school, leaving the athletes still in limbo time to find their ideal fit.

The NCAA basketball transfer portal window officially closes on Wednesday, after an active period saw top players unafraid to jump ship — even if that means joining a rival team.

After the portal window shuts, athletes can no longer declare their intention to transfer, though there's no official deadline for accepting admission to a new school.

Former UCLA rising senior Londynn Jones is the latest to switch sides, taking her 35.1% three-point shooting to the Bruins’ fiercest Big Ten competition by committing to crosstown rival USC on Tuesday.

The SEC — arguably the sport's powerhouse conference — has also seen significant movement in recent weeks, with Ole Miss landing ex-Ohio State standout Cotie McMahon and ex-Mississippi State guard Denim DeShields — WNBA veteran Diamond DeShields’s little sister.

Maryland is also cleaning up, signing ex-Duke star guard Oluchi Okananwa and Indiana center Yarden Garzon to the Terps' 2025/26 roster.

Meanwhile, 2025 national championship runner-up South Carolina added former Mississippi State big Madina Okot on Monday, after securing ex-Florida State guard and Division I's 2024/25 scoring leader Ta’Niya Latson earlier this month.

Another transfer portal superstar considers a jump

As the stars begin to settle, all eyes are on South Carolina transfer MiLaysia Fulwiley as she weighs her options ahead of her junior year.

Like UCLA-to-USC transfer Jones, the Columbia, South Carolina, product could opt to go the rival route, with rumors of Fulwiley seriously eyeing SEC foe LSU currently making the rounds.

All in all, while the player pool will be finalized on Wednesday, it could take days, weeks, or months to round out NCAA basketball rosters, as teams continue courting athletes in the portal before the 2025/26 season tips off.

With just 16 teams remaining in this year's March Madness tournament, NCAA programs that have fallen from contention have athletes jumping into the transfer portal, which opened to all college basketball players on Monday.

Multiple players are now seeking to make an offseason move, including this season's Division I leading scorer, Florida State junior guard Ta'Niyah Latson.

After averaging 25.2 points per game throughout her 2024/25 campaign, the National Player of the Year semifinalist jumped into the portal on Thursday, three days after the No. 6-seed Seminoles fell 101-71 to No. 3-seed LSU in Monday's second round.

The All-ACC standout is exploring her transfer options — and the potential NIL windfall a move could bring her — though remaining at Florida State is reportedly still very much on the table.

Another top prospect eyeing an exit is Cotie McMahon, who joined the transfer race on Wednesday following her No. 4-seed Ohio State's 82-67 second-round March Madness loss to No. 5-seed Tennessee.

The 2023 Big Ten Freshman of the Year and two-time All-Big Ten First Team selectee looks to carry her career-best 16.5 points per game average elsewhere for her final year of collegiate eligibility.

More top teams see players take to the transfer portal

Other freshly eliminated programs have also seen portal movement, with players from No. 4-seed Kentucky, No. 7-seed Louisville, and No. 8-seed Georgia Tech all testing the transfer waters.

Notably, the program with the most athletes fleeing is No. 9-seed Indiana, who has seen five of their nine non-graduating players enter the portal in the last three days — including every Hoosier who earned minutes off the bench in the team's two March Madness matchups.

With athletes weighing everything from playing time to NIL paydays to postseason potential, the current NCAA landscape boasts multiple factors motivating decisions to either jump ship or weather the storm.

As the 2025 March Madness tournament rolls on, expect even bigger college basketball names to throw their hats into the transfer ring, as players seek out top programs ahead of the 2025/26 NCAA season.
