The Morris twins were nearly unstoppable during those moments, combining for 40 points and 21 rebounds. Marcus had his third straight double double.
But Colorado, led by Alec Burks, mounted quite the charge, cutting the lead to six points late. The Kansas City, Mo. native led all scorers with 23 points.
This game exposed a problem with KU (31-2). The past two games, they have come out flat in the opening minutes and have to ramp themselves up in the second to win. They can't do that if they want to win yet another Big 12 title game.
"We've got to do a better job of coming out hard and prepared and ready to go," said Tyrel Reed, KU guard. He had 15 points against the Buffaloes and hit a clutch three-point shot that pulled them out a scoring lull in the second half.
"We just hunkered down and defended and I think we did a lot better job of keeping the ball in front of us and getting stops and that gives us confidence with the ball."
As long as the Morris twins are firing on all cylinders, Kansas will rely on them to keep the Jayhawks winning, leaving teams at a disadvantage.
"Putting so much emphasis on one player, and then I'm there, it's hard to guard both of us," said Markieff Morris. "I think that when we are on the court together and playing well, its a tough matchup for a good team."
