Tubby Smith said video from the Gophers' 87-79 loss to Virginia on Monday confirmed what he suspected about his team's defensive problems.
"After watching the film, the Virginia game, it was as bad as I thought it was," the coach said Friday, a day before the Gophers were to play host to Cornell. "We really didn't defend like we should."
He added: "Teams that win are teams that usually have the best shooting percentage and can figure out a way to stop you, and [Virginia] did that. The last few days, we've been working on correcting some of the defensive mistakes we made."
Trevor Mbakwe said players endured more running and "Tubby stares" than usual this week in practice. But he said they understand the staff's reaction and don't want to repeat their mistakes from the program's first nonconference home loss in four seasons under Smith. They surrendered 58 points to the Cavaliers in the second half.
"It was just an embarrassment, really, when we watched the film," said Mbakwe, a junior forward averaging 14.3 points and 9.3 rebounds per game. "We were letting them go wherever, do whatever they wanted to do in the second half. And we pride ourselves on defense. So watching that, it was pretty embarrassing for us as players."
Smith said he hopes Monday's loss gave the 15th-ranked Gophers a reality check after they got off to a 6-0 start, including victories over North Carolina and West Virginia on their way to winning the Puerto Rico Tip-Off.
"I didn't think we needed a wake-up call, but if we can use it as that, we will use it as that," Smith said. "Good teams will expose you, and that's what happened. I'm sure [Gophers players] won't be overconfident now. I think we got that across the last couple of days."
After Monday's game, Smith told his players that he wished one of them would "evolve" into a stubborn defender like 2009-10 senior co-captain Damian Johnson, who attended Monday's game.
