PROVO, Utah (Interstat) — In a rivalry defined by fervent crowds and close contests, the latest chapter was instead a showcase of one team’s overwhelming firepower. The No. 1-ranked BYU Cougars, behind a dominant 43-point performance from star forward AJ Dybantsa, pulled away from the Utah Utes for a decisive 91-78 victory before a sellout crowd of 18,224 at the Marriott Center on Saturday.

The win improved BYU’s record to 16-2 overall and completed a regular-season sweep of its in-state rival, having also won in Salt Lake City 89-84 just two weeks prior. Utah, despite a valiant offensive effort, fell to 9-11.

The game’s most critical sequence unfolded late in the first half, transforming a competitive battle into a contest BYU would control the rest of the way. With Utah leading 32-30 after a layup by Seydou Traore with 3:45 remaining, the Cougars unleashed a devastating 12-5 run to close the period. The surge was capped by a Dybantsa 3-pointer assisted by Khadim Mboup with 22 seconds left, giving BYU a 42-37 halftime advantage it would not relinquish.

That momentum carried into the second half, where BYU’s offensive efficiency and interior dominance became insurmountable. The Cougars shot a scalding 53.3% from the field for the game and owned the paint, outscoring Utah 48-18 near the basket. They complemented that with a 19-of-23 showing from the free-throw line. Utah, while remarkably efficient from deep at 13-of-21 and perfect on 11 free throws, could not counter BYU’s consistent high-percentage offense, which posted an offensive rating of 134.0 points per 100 possessions.

Dybantsa, a 6-foot-9 freshman from Brockton, Massachusetts, was the central figure. He played 35 minutes, making 14 field goals and adding 11 free throws for his game-high 43 points. He also contributed three assists, a block and a steal, orchestrating the offense from the forward position. His performance was a stark escalation from his recent outings, including a 25-point game against TCU, and proved too multifaceted for Utah to contain.

He was supported ably by guard Robert Wright, who added 21 points and three assists, and forward Richie Saunders, who chipped in 12 points. BYU’s defense also made its presence felt with five blocks and five steals, disrupting Utah’s rhythm at key moments.

Utah’s effort was led by the backcourt duo of Keanu Dawes and Terrence Brown. Dawes, a 6-foot-9 guard from Houston, scored 23 points, while Brown, a guard from Minneapolis, finished with 22 points and four assists. Don McHenry added 16 points for the Utes, who shot 45.8% overall and committed only six turnovers but were hampered by a lack of offensive rebounds and assists, managing just four of each.

The second half saw BYU methodically extend its lead. After Utah drew within 49-46 on a Brown 3-pointer early in the period, the Cougars responded with a 6-0 spurt. Dybantsa was again at the heart of it, completing a three-point play after a layup and then drawing fouls to hit free throws. BYU’s lead ballooned to as many as 16 points in the final minutes before settling on the 13-point final margin.

The victory reinforces BYU’s status as a national contender, with its two losses coming by narrow margins to Connecticut and Texas Tech on the road. Utah, meanwhile, continues to search for consistency in a demanding conference schedule, having now lost three of its last four games.

BYU faces a quick turnaround, hosting Arizona on Monday. Utah’s next game is at home against Oklahoma State on Jan. 31.
