No, the lights never dimmed during the ACC/Big 12 Challenge between North Carolina's women's basketball team and Oklahoma.
But the Sooners effectively sucked the power out of UNC's top guards, Coretta Brown and Juana Brown.
Before Sunday's matchup both Browns had been playing near the top of their games. Juana Brown was averaging 13.8 points per game and boasted a free-throw percentage of 71.8. She was on fire in UNC's trouncing of Florida State last Thursday, contributing 21 points and seven steals.
There wasn't even a spark of that fire seen against Oklahoma.
Juana Brown shot a disappointing 5-for-17 from the field. And not all of those shots could be contributed to the Sooners' defensive skills. She didn't sink her open looks either.
"I think it was really an off day," Brown said. "I don't want to take anything away from Oklahoma's defense, because their defense was pretty good. But a lot of times, my shots were open shots; I just didn't make them."
Brown not only had trouble connecting from the paint, she also struggled outside the arc. She shot 2-for-9 on 3-point attempts, her worst performance since the second game of the season.
When one Brown starts having trouble, typically the other Brown helps out.
But Coretta Brown, who scored more than 20 points in two of her last three games, also shot 5-of-17.
