Courtney Ramey scored 18 points to lead five Texas players in double figures, and No. 8 Longhorns routed third-ranked Kansas 84-59 on Saturday to match the most lopsided win by an opponent in the history of Allen Fieldhouse.

Andrew Jones added 14 points, Matt Coleman III had 13 and Jericho Sims had 11 points and 12 rebounds for the Longhorns (8-1, 2-0 Big 12), who turned an eight-point halftime lead into a blowout in startling fashion.

The margin of victory was the most by an opponent in the Phog since Missouri's 91-66 victory on Feb. 1, 1989.

"Certainly we didn't do anything to stop them," Kansas coach Bill Self said. "We already got our ass kicked once today; we didn't need to have it kicked again in the locker room. But we got to regroup, we got to decide if we want to be a team that makes other people play bad, and that what we take the most pride in, because they certainly didn't look like that today."

Jalen Wilson scored 20 points and Ochai Agbaji had 11 for the Jayhawks (8-2, 1-1), who shot 31% from the field and went just 3-of-23 from beyond the arc in losing their first game since their opener against top-ranked Gonzaga.

"The message is pretty obvious: This doesn't happen in the Fieldhouse,'' Wilson said. "This is very embarrassing. We're a good team and today we didn't show what we're capable of.''

Coincidentally, it was the first top-10 matchup for Texas in a Big 12 regular-season game since it beat then-No. 2 Kansas on Jan. 22, 2011. The win also snapped a three-game skid against the Jayhawks, who had won 16 of 17 against the Longhorns and had been 16-1 against them in games played inside 65-year-old Allen Fieldhouse.

Kansas hadn't taken the floor since Dec. 22, when it routed seventh-ranked West Virginia. The 12-day layoff was the longest in the regular season under Bill Self, who took over the program before the 2003-04 season.

The Longhorns had been off even longer. Thanks to an uptick in COVID-19 positives at Texas A&M Corpus-Christi, their game Tuesday night was canceled. That left Texas without a game since it beat Oklahoma State on Dec. 20.

"I'm just happy for our guys. They put so much energy and time and effort into everything,'' said coach Shaka Smart, whose Longhorns never trailed. "These last several months and having guys canceled and guys having things up in the air, having a couple guys unavailable, but the guys just hung in there and controlled what they could control.''

Kansas missed its first eight shots and finished 1-of-7 from beyond the arc in the first half. Texas fared little better from 3-point range and coughed up 10 turnovers, although a late run fueled by Kai Jones off the bench resulted in a 37-29 halftime lead.

The Jayhawks trimmed their deficit to four early in the second half, but consecutive 3-pointers by Andrew Jones (who had been 1-for-8 from the field) Coleman and Ramey gave Texas its biggest lead at 50-38 with 15:42 to go.

Relying on their experience, the Longhorns refused to pull back on the pressure. They began to create turnovers on the defensive end that led to easy layups, and their outside shooting continued to sizzle. Their advantage swelled to 63-47 with 8:51 to go, forcing Self to call a timeout -- only for the Jayhawks to immediately turn it over again.

Sims added a dunk, Donovan Williams a 3 and Self burned another timeout as the Texas lead stretched.

At that point, it looked as if the Longhorns would have a shot at the most lopsided win by an opponent in Allen Fieldhouse history. Tyon Grant-Foster's basket with just over a minute left prevented that from happening.

"The biggest thing I said when we got into the locker room after the game is, 'We're supposed to do this,''' Ramey said. "This shouldn't be a shock or a surprise. When you go [and] be us, you come out with a dominant performance. Now we have to keep it rolling.''

THOMPSON SITS

The Jayhawks played without Bryce Thompson, their top player off the bench, after Self said the freshman guard hurt his back on "a hard fall in a bad spot" in practice. Thompson is averaging 5.4 points in 17.5 minutes per game.

BIG PICTURE

Texas followed the blueprint for beating the Jayhawks perfectly. It shut down the perimeter, where Kansas had been so good in its win over West Virginia, and dominated on the glass to prevent second-chance opportunities.

Kansas dealt with a much longer team in beating then-No. 20 Kentucky earlier this season. But the Jayhawks struggled with what Texas brought to the floor. Big man David McCormack was entirely ineffective in the paint, and their guards, who rely on slashing through the lane to create shots, kept finding their path blocked by burnt orange.
