A strange sequence of events in the first half cost Kansas a possession at the start of the second half, leaving KU coach Bill Self a little heated during a dispute at halftime.

Here’s how it happened: With 8:11 left in the first half, there was a jump ball and Texas Tech was awarded possession, based on the possession arrow. As the Red Raiders took the ball out, Texas Tech’s Jaye Crockett was called for a dead-ball foul. KU took possession, but since no time had run off the clock, the possession arrow stayed with Texas Tech.

When this became clear at halftime, Self pleaded with official John Higgins to no avail.

“To me, that makes zero sense,” Self said. “But they said that was the rule. And I’m sure they’re right. They said they had it other times. But that’s one (rule) that may need to be visited.”

After conferring with other KU officials after the game, Self was still certain that the rule penalized his team for making a positive play.

“A foul is a turnover,” Self said. “So that’s a bad rule, and I would argue anybody on that one.”

•  Kansas scored a season-low 60 points, its lowest output since scoring 59 in the NCAA title game against Kentucky.

• Freshman guard Ben McLemore made six of eight from the free-throw line, making him 56 for 64 (87.5 percent) for the season.

• Texas Tech guard Jamal Williams Jr. started in place of Trency Jackson, who was reportedly suspended for a violation of team rules. Williams led Texas Tech with 11 points.
