APPLETON, Wis. — The men's college basketball transfer portal swung open just minutes after Michigan's triumphant buzzer-beater secured the national championship over UConn on Monday night, marking the start of what promises to be the busiest offseason shakeup in recent memory. By Tuesday morning, more than 1,000 Division I players had entered their names, according to ESPN, with projections suggesting the total could eclipse 3,000 entrants this cycle—surpassing the roughly 2,100 from 2024 and nearly 2,700 the previous year.
The portal's launch came at 11:20 p.m. ET, mere moments after the confetti fell in the championship game, and new NCAA rules have reshaped the landscape for all sports. For men's basketball, the window remains open for two weeks, from April 7 to April 21, giving players and programs a compressed timeframe to navigate commitments and roster rebuilds. Coaches across the country anticipate a frenzy, as teams look to plug holes left by departing stars and incoming freshmen.
At the forefront of this migration are some of the sport's most talented underclassmen and veterans, with ESPN ranking the top 20 players to hit the portal as of 5 p.m. ET on April 7. Leading the pack is Flory Bidunga, a 6-foot-10 power forward and sophomore from Kansas, who exploded onto the scene this season. Bidunga elevated his game dramatically, jumping from 5.9 points and 5.4 rebounds per game as a freshman to 13.3 points, 9.0 rebounds, and a league-leading 2.6 blocks in 2025-26, according to ESPN analysts. He shot an impressive 64% from the floor and notched 13 double-doubles, earning all-Big 12 honors as one of the elite post defenders in college hoops.
Bidunga's departure from Kansas leaves a void in the paint for the Jayhawks, who relied on his rim protection and scoring touch. "He's a plug-and-play player," ESPN noted in its breakdown, highlighting his immediate impact potential at any program. His breakout year positions him as a prime target for title contenders seeking frontcourt dominance.
Close behind at No. 2 is John Blackwell, a 6-4 shooting guard and junior transferring from Wisconsin. Blackwell's scoring prowess made him one of the most explosive wings in the nation, averaging 19.1 points and 5.1 rebounds while connecting on nearly 39% of his three-point attempts. After thriving off the ball alongside Nick Boyd for the Badgers, Blackwell is seeking a larger playmaking role at his next destination, per the ESPN ranking.
The third spot goes to Juke Harris, a 6-7 sophomore shooting guard from Wake Forest, whose scoring surge turned heads in Winston-Salem. Harris leaped from 6.1 points as a freshman to 21.4 as a sophomore, placing him in the national top 20 for scoring. He delivered three 30-plus point outings, including a blistering 38 points in just 39 minutes against Boston College, showcasing his ability to take over games.
International flavor adds intrigue to the list, with No. 4 Paulius Murauskas, a 6-8 junior forward from Saint Mary's, entering the portal shortly after coach Randy Bennett's move to Arizona State. The Lithuanian, who began his career at Arizona, earned All-West Coast Conference nods in each of the last two seasons. This year, he averaged 18.4 points, 7.6 rebounds, and 2.1 assists, solidifying his status as a versatile scorer and rebounder.
Freshman sensations are well-represented, including No. 5 Stefan Vaaks, a 6-7 shooting guard from Providence. The Estonian native surprised as a versatile perimeter threat, averaging nearly 16 points and 3.2 assists. Vaaks lit up big-name foes, scoring 20-plus points against St. John's (twice), Villanova (twice), and UConn, demonstrating his positional size and dual-threat capabilities as a scorer and facilitator.
Another freshman standout, No. 6 Isaiah Johnson, a 6-1 guard from Colorado, earned All-Big 12 honorable mention honors. The Los Angeles product burst out with 24 points in his debut against Montana State and maintained momentum, dropping 27 on BYU and 28 on Arizona en route to 16.9 points and 3.0 assists per game.
Injuries have plagued some top talents, like No. 7 Jackson Shelstad, a 6-1 junior point guard from Oregon. Shelstad was en route to All-Big Ten recognition before a December hand injury sidelined him after 12 games, where he posted 15.6 points and 4.9 assists. His sophomore year had already netted third-team All-Big Ten acclaim, underscoring his potential as one of the conference's top guards.
Villanova's Acaden Lewis, ranked No. 8, is a 6-2 freshman point guard who flipped his commitment from Kentucky to the Wildcats last spring. Lewis dazzled with 12.2 points, 3.0 rebounds, 5.3 assists, and 1.9 steals, including seven 20-plus point games. ESPN analysts suggest that honing his three-point shot could propel him to elite status among point guards.
Down low, No. 9 Moustapha Thiam, a 7-2 sophomore center from Cincinnati, flashed immense upside late in the season. In a February stretch, he tallied 28 points and eight rebounds against Kansas, 21 points and 10 boards versus Texas Tech, and 24 points with 15 rebounds over Oklahoma State. For the year, Thiam averaged 12.8 points, 7.1 rebounds, and 1.6 blocks.
No. 10 Markus Burton, a 6-0 junior point guard from Notre Dame, has battled injuries over three seasons but delivered when healthy. In 69 games, he averaged 19.1 points, 3.4 rebounds, and 3.8 assists, shooting just over 33% from beyond the arc. His resilience makes him a valuable asset for programs needing a proven scorer.
Former blue-chip recruit Donnie Freeman, No. 11, a 6-9 sophomore power forward from Syracuse, rounds out the top dozen. A top-10 high school prospect in the 2024 class, Freeman averaged 16.5 points and 7.2 rebounds this season, earning honorable mention All-ACC honors despite an early nonconference injury. He exploded for six 22-plus point games against ACC foes.
The rankings continue with versatile defenders like No. 12 Miles Byrd, a 6-6 junior shooting guard from San Diego State, who averaged double figures in scoring for the second straight year while racking up over three combined blocks and steals per game. Byrd, who returned from NBA draft consideration last spring, is prized for his two-way impact.
VCU's Terrence Hill Jr., No. 13, a 6-3 sophomore shooting guard, boosted his profile with a 34-point masterpiece in a first-round NCAA tournament upset over North Carolina, fueling a 19-point comeback. The first-team All-Atlantic 10 selection averaged 15.0 points, shooting 37% from three.
Point guard demand is high for No. 14 Dedan Thomas Jr., a 6-1 junior from LSU, limited to 16 games by a hand injury but still averaging 15.3 points and 6.5 assists. After two seasons at UNLV, Thomas had the Tigers eyeing postseason glory when healthy.
Sananda Fru, No. 15, a 6-11 junior center from Louisville, impresses with efficiency, shooting over 75% from the field in averaging 9.0 points, 6.1 rebounds, and 1.4 blocks in 22 minutes per game. The German big man's analytics darling status marks him as an instant starter at the high-major level.
Georgetown's KJ Lewis, No. 16, a 6-4 junior shooting guard, enters for the second straight year after transferring from Arizona for a bigger role. He averaged nearly 15 points, improved his three-point shooting, and brought All-Big East physicality on defense.
Virginia Tech freshman Neoklis Avdalas, No. 17, a 6-9 guard, opened eyes with 33 points, five rebounds, and six assists in his second college game against Providence. Though inconsistent later, his 12.1 points and 4.6 rebounds highlight untapped potential from his size-skill combo.
Alabama's Aiden Sherrell, No. 18, a 6-10 sophomore power forward, saw his role expand under coach Nate Oats, jumping to 11.1 points and 6.2 rebounds in SEC play from 3.4 and 2.8 earlier. Highlights included 15 points and 15 rebounds in an NCAA win over Hofstra and 26 points with 13 boards against Arkansas in February.
Georgia's Somtochukwu Cyril, No. 19, a 6-11 sophomore center from Nigeria, progressed to 9.3 points, 5.4 rebounds, and 2.2 blocks, shooting nearly 76% from the field. As one of the top rim protectors, he hit double figures 10 times in SEC action.
Rounding out the top 20 is NC State's Matt Able, No. 20, a 6-6 freshman shooting guard and former top-25 recruit who tested the NBA draft waters. Despite inconsistency under coach Will Wade, Able averaged 8.8 points and shot 35.5% from three, showing flashes of one-and-done caliber.
ESPN plans to expand its rankings to 100 players in the coming days and weeks, tracking commitments and providing analysis as the portal evolves. This influx of talent underscores the shifting dynamics of college basketball, where immediate eligibility rules and NIL opportunities empower players to chase better fits. Programs like Kansas, Wisconsin, and Wake Forest now face roster overhauls, while suitors line up for these difference-makers.
