I feel good that our team is moving the right direction, but we're not completing games. We have to work hard defense for 40 minutes."

"We tried to catch up by using our pressure," said Crook, who made 5 of 10 shots. "We took advantage and scored after creating turnovers."
"This team (Cal) is an inside team," said Cooper. "We had to stay close to them so they wouldn't kill us on the boards.
