“For about 2 1/2 minutes … until we were behind 6-0,” Self, the former Oklahoma State player and assistant coach, said after his alma mater’s basketball team hammered his Jayhawks, 80-60, Monday night at Gallagher-Iba Arena.

The rout, which gave No. 10-ranked Oklahoma State (18-2 overall, 8-1 Big 12 Conference) sole possession of first place in the league, began just moments after Self received loud cheers during pregame introductions.

“I had a chance to see some people and tour the place. It was nice what the crowd did for me,” Self said. “Their crowd was awesome, as was their team. I told our guys that’s how basketball is meant to be played.”

OSU excelled in all areas early and often in blowing out the No. 12-rated Jayhawks (15-5, 7-2).

The Cowboys, coached by Self’s former boss, Eddie Sutton, hit:

• their first five shots in building a 13-4 lead,
• seven of eight in building an 18-6 lead,
• eight of nine in building a 20-6 lead,
• nine of 10 in building a 23-6 lead,
• and 10 of 12, including six of seven threes, in rocketing to a 26-8 advantage with 12:46 left in the half.

KU would get no closer than 14 the rest of the way in suffering its worst defeat since a 84-53 loss to Wake Forest Dec. 7, 2000.

“We were shell-shocked when they jumped out 10, 12, 14 right off the bat,” Self said. “It took us out of our game. I hate to say that was the ballgame, but it’s what it played out to be,” Self added. “There’s still 32 minutes to play. We played so bad it wouldn’t have mattered if it was a 60-minute game.”

Five ‘Pokes scored in double figures, led by John Lucas, who had 21 points off 7-of-9 shooting, including three of five threes. He had 14 the first half as OSU blazed to a 44-26 advantage. Numerous timeouts by Self did nothing to quiet the Cowboys or their fans.

Tony Allen scored 17, Ivan McFarlin 12, Daniel Bobik 11 and Joey Graham 10, while KU had only Wayne Simien (25 points) and J.R. Giddens (12) in double figures.

“You saw the game. There was only one guy on our team who by performance would have been able to play for Oklahoma State,” Self said. “That would have been Wayne. The rest of our guys didn’t have their game tonight.”

Point guard Aaron Miles suffered six turnovers and had just three points compared to Lucas, his counterpart point guard, who had 21 points. Keith Langford went 2-for-10 shooting and had eight points, scoring in single digits for the second straight game after his run of 32 straight games in double-figure scoring.

Perhaps the worst stat of all for KU — even worse than 5-of-14 three-point shooting and 5-of-15 free throwing — was rebounding. KU was outboarded 43-26.

“It didn’t shock me,” Self said, “but it was disappointing. They were athletic and quicker than us. We don’t do a good job of chasing the basketball.

“The most disappointing thing is, they physically dominated the glass.”

The ‘Pokes set their dominant tone early.

“They are so explosive and athletic,” Self said. “Our first two possessions … we got layups. Aaron misses a layup; Keith got a layup blocked. It was downhill from there.

Langford had an early airball and also airballed a free throw in a first half he and his teammates obviously would like to forget.

“It’s tough to dig a hole against a team that good,” Langford said. “The only person who played was Wayne. Everybody else didn’t have it.”

Not even Self, who called a batch of timeouts to go with TV timeouts to no avail.

“It didn’t stop the momentum,” Langford said. “It’s the players fault. Coach Self can only do so much over there. We’ve got to play.”

The Jayhawks never really scared the Cowboys.

“They came out the first half and hit some incredible shots,” Simien said of OSU, which made six of eight threes the first half. “They were scoring off our turnovers.

“Once they hit some shots, dunks, the crowd got into it and picked up the enthusiasm.”

Simien figured KU would regroup at halftime, down 18.

“I didn’t think we were out of it because last year we were down 32 against Oklahoma and scrapped back to single digits. They scored on their first three possessions of the second half, and we dug too big a hole again.”

KU, which dropped to third in the league (Texas is 6-1), will meet Nebraska at 12:30 p.m. Sunday in Lincoln, Neb.
