The Longhorns' defense appeared to be heading towards another year of mistakes, blown coverages and poor tackling in their season-opening loss to Maryland. They gave up 51 points to the 17-point underdog in the defeat.But defensive coordinator Todd Orlando's group has done a complete 180 since week one. For the third straight game, Texas' defense stifled its opponent for the full 60 minutes."They learned a very costly, but valuable lesson in that Maryland game," Herman said.
