The comforts of home got a little too cozy for the Colorado women's basketball team on Thursday.

Playing at Coors Events Center for the first time in nearly a month, the Buffs built a 12-point lead and appeared poised to run away from California.

During the final 12 minutes, however, it was Cal that looked most at ease in its surroundings, rolling to a 68-55 win over the Buffs.

"I think we just got extremely too comfortable," said CU junior Chucky Jeffery, who led all scorers with 21 points. "Being at home, we just get too comfortable and I think that's what really got us."

Jeffery scored five straight points to give the Buffs (13-2, 2-2 Pac-12) a 51-39 lead with 12:45 to go. From that point, Cal (12-5, 3-2) outscored the Buffs 29-4, including 17-0 in the final 7 minutes.

"Well, we're disappointed," CU head coach Linda Lappe said. "Against these teams (in the Pac-12), we have to play a full 40 minutes. We didn't play a full 40 minutes. We played about 32 minutes."

Colorado fell behind by 11 in the first half -- its largest first-half deficit of the season -- but closed the half on an impressive 29-11 run.

The Buffs continued their strong play early in the second half. Their defense came up with stops. They were out-rebounding the No. 1 rebounding team in the country. And Jeffery piled up 10 points in the first 71/2 minutes of the half, giving CU it's biggest lead of the game, 51-39.

"Those first 32 minutes, I think we were doing exactly what the game-plan was," Jeffery said. "We felt like we were doing everything that we needed to, keeping them off the offensive glass and taking care of the ball. That's what we got away from in the second half."

Cal then switched to a zone defense, and the complexion of the game changed.

"I felt like we had some good shots against the zone," Lappe said. "We're a 3-point shooting team, so I felt like you've got to step up and knock some shots down. I think if we would have done that the first couple of times, I don't think we would have seen the zone again. When that didn't happen, they stayed with it and they kept changing it up."

Just getting looks at the basket proved to be a challenge, though, because after going nearly 20 minutes without a turnover, CU couldn't stop coughing up the ball in the final 12 minutes.

"We started turning the ball over, so we were sprinting back in transition and they got a couple of easy baskets to turn the momentum in their favor," Lappe said. "That hurt a lot."

Everything CU did well to get the lead turned sour, especially in the paint. After flexing its muscle against Cal's post players early, Cal showed its strength on the glass in the final 12 minutes.

"We stopped boxing out," Lappe said. "They had 10 offensive rebounds in the second half. We were leading them on the boards and then stopped doing that and put them at the free throw line."

Cal has burned teams all year with offensive rebounds and second-chance points. CU held the Bears without a second-chance point in the first half, but Cal had 12 of those after intermission. The Bears also hit some outside shots. Guards Layshia Clarendon (18 points) and Brittany Boyd (12) had big games, while forward Gennifer Brandon had 17 points.

"I told them that I am as proud of this win as any that we have had all season," Cal coach Lindsay Gottlieb said. "I really thought our players stepped up. We played like a team and our depth came through.

"I'm very proud of our defensive effort down the stretch and just our ability to suck it up and say, 'We can win from behind. We can win at altitude. We can win on the road.'"

Colorado's inability to show that resolve down the stretch left the Buffs stunned and deflated. Now, they've got one day to prepare for No. 4 Stanford, which visits Saturday.

"I think it's always tough (to have one day), but the good thing is you can get rid of this one fast," Lappe said. "We watch it and move on."
