LAWRENCE, Kansas (Ticker) -- Nick Collison and Wayne Simien were double trouble inside against Colorado.
Collison collected 24 points and 14 rebounds and Simien added 21 and 13 as sixth-ranked Kansas avenged its only Big 12 Conference defeat with a 94-87 triumph over the Buffaloes.
"(Simien) and Collison, I think, are the best combination of post players in the league," Colorado coach Ricardo Patton said. "They do an excellent job of feeding off one another. They do as good a job as any two post players I have seen in a very long time."
Kirk Hinrich added 14 points, Aaron Miles 12 and Keith Langford 11 for the Jayhawks (20-5, 10-1 Big 12), who lost at Colorado on January 22, 60-59. That snapped a 27-game winning streak by Kansas in the series.
In this one, Kansas took a 46-38 advantage into the second half after Colorado's Michel Morandais nailed a shot from well beyond midcourt at the halftime buzzer. The Jayhawks did not allow the Buffaloes to gain any momentum from the shot, opening the second half on a 24-9 run.
It was the Jayhawks' 20th consecutive home victory over the Buffaloes. With the win, Kansas opened a one-game lead over Texas and the winner of Wednesday's Oklahoma-Oklahoma State matchup in the Big 12.
Paced by Collison and Simien, who was playing his second straight game after missing the previous 11 with a separated shoulder, the Jayhawks outrebounded the Buffaloes, 46-38, and outscored them in the paint, 48-30.
"It was maybe as tough as a performance as I have ever seen by a kid who has an injury," Kansas coach Roy Williams said. "You can't describe it. ... What he did was mind-boggling. I am as proud as I can be to be involved with Wayne Simien."
"I reached out a little bit," Simien said. "It goes along with a discipline thing where I try not to put my arm in a bad situation. Sometimes instinct overrides that discipline."
Kansas notched its seventh straight victory and improved to 26-1 in conference play over the last two seasons.
Morandais scored 28 points, Blair Wilson 21 and David Harrison 20 for Colorado (15-9, 5-6), which fell to 0-6 on the road in conference play.
"I really do think they are a good team," Williams said. "They just haven't been fortunate enough to break through on the road. We wanted to make sure that it did not happen here tonight."
Morandais and Wilson each nailed three 3-pointers for the Buffaloes, who used their outside shooting to reduce a 23-point Kansas lead to five in the final 10 seconds, but it was too little, too late.
"We took our best shot," Morandais said. "We were down 20 or more, then we got on a run and we came back and closed the gap. We have to find a way to finish, and we will. We have two more road games, so we will find a way to win. There are no more moral victories. This late in the season, everyone is trying to make a push for the NCAA Tournament, so a loss is a loss."
"They kept coming at us and then we made some of the dumbest plays you have ever seen," Williams said. "I am as happy as I can be to get the win. We've got to be a lot smarter but still, Nick Collison, Wayne Simien - that's big-time basketball."
