Barry Brown missed a potential game-winner at Kansas on Saturday, an off-balance shot he was not supposed to take, and spent the next couple of days ruing the missed opportunity. Kansas State’s junior guard made up for it Tuesday night. Brown poured in 24 points, locked down defensively on Oklahoma freshman Trae Young, and ultimately led the defensive-minded Wildcats to an 87-69 rout of the fourth-ranked Sooners. “Barry did everything,” Kansas State head coach Bruce Weber said.
