Julien Lewis led Texas with 15 points off the bench, but OSU held Myck Kabongo – averaging 18.6 points in five games since his return from suspension – to seven points with seven turnovers.
Still, it took a while for the Cowboys to engage.
The Longhorns led 15-7 barely more than six minutes in, as the Cowboys were turning it over and missing shots.
“In the first half, it was all about them making 3s and us turning the ball over,” said OSU coach Travis Ford. “But we had the one big spurt that really ignited us, and it came from our defense and our pressing.
“Our press was pretty effective for most of the night. And I thought our overall defense was good. When we didn't turn the ball over, we defended them extremely well, especially in the second half.”
Texas still led 22-21, when Kirby Gardner produced a steal and fed Brown streaking ahead.
Moments later, Brown put a hammer on the Horns.
As for the exalted status the dunk receives on his favorite play list, Brown said it all has to do with degree of difficulty.
“I feel it was a difficult dunk to do,” he said. “And to do it on a big stage and in front of a big crowd is exciting to do.
“I also think my teammates like that dunk. They've been telling me to do that dunk. When I finally got the chance, I did it.”
Apparently, it's been a team favorite, too, with Brown perfecting it in practices and on the side.
“We'll get to that when it comes,” said Brian Williams. “I don't want to share anything.”
Still, Brown had a SportsCenter moment that was already making the rounds early Saturday. And he and his teammates were wondering where it might rank on ESPN's Top 10 Plays.
Williams: “I'm tuning in.”
Nash: “I hope it's No. 1.”
Brown: “It better be No. 1.”
