The problem was the Sooners were playing arguably the best offensive team in the country.
No. 3 Kansas shot lights out for more than a half to build a comfortable lead en route to an 82-70 win in front of 8,700 fans, nearly half wearing KU blue.
"Kansas is a great basketball team, incredibly efficient on the offensive end," said OU coach Jeff Capel. "We tried as much as we could that first half to stop them. It was kind of pick your poison... They were in great rhythm."
Kansas leads the nation in field goal percentage (52.1) and is fourth in scoring (83.8).
But for more than a half the Jayhawks were on fire even by their lofty standards.
The Jayhawks hit 17 of their first 22 shots, a blistering 77.3 percent, to build a double-digit lead late in the first half. Kansas led by double digits the entire second half.
"Offensively the first 16 to 17 minutes we were terrific," said KU coach Bill Self. "We only missed two shots inside the arc the first half. I look up and we're only up 12. We obviously didn't guard well but they're so unselfish."
So are the Jayhawks.
Led by the Morris twins, Markieff and Marcus, who combined for 42 points and 19 rebounds, the Jayhawks took advantage of an inside mismatch.
"Those guys can shoot it. They're skilled," Capel said. "They can play with their backs to the basket. They can pass it. They're very good... I'm just impressed with everything about their game."
Because of a size disadvantage, OU tried to double team the Morris twins but Kansas also leads the nation in assists.
The Jayhawks (27-2, 12-2 in league play) made the extra pass to get open looks.
"They share the ball really well," said OU guard Cade Davis. "They weren't missing any shots from the outside which got us down early... It's frustrating. We're on the help side, rotating. They did a real good job of swinging the ball to find the open man."
OU's losing streak is now seven but the Sooners didn't play poorly against a team that's expected to get a No. 1 seed in the NCAA Tournament.
The most glaring stat was KU dominated the boards 35-16. The Jayhawks grabbed nearly as many offensive rebounds (12) has OU had total.
"We knew we would be at a size disadvantage like we are most games," Capel said. "But I thought we could have fought a little bit more on the boards with block outs and being physical... But our guys fought throughout the game."
Trailing by as many as 21 points, the Sooners closed to within 75-64 with 4:24 remaining but would never get closer.
"They're well coached and they play hard," Self said. "We could have broken the game open but they didn't go away."
