NORMAN — It took Oklahoma senior Kenneth Mann awhile to really get acclimated to Alex Grinch's defense.
The defensive end who was a captain on last year's team was injured in the spring and didn't return to action until Sept. 28 against Texas Tech.
Ahead of Saturday's game against Texas (11 a.m., Fox), Mann praised the work Grinch has done helping to turn around the Sooners' defense.
"He's brought energy and he's brought a clear-cut plan for us," Mann said. "There's no grey area. We know what we need to do and he's emphasizing the same message to us every single day.
