Associated Press BOISE, Idaho -- For years, Boise State's defense has taken a back seat to the Broncos' clever, high-scoring offense. But this year, the defense is taking every opportunity to change that perception. Thanks to a fourth-quarter goal-line stand, a stifling run defense and constant quarterback pressure, it was the defense that led the 17th-ranked Broncos to a 38-3 victory over Louisiana Tech on Wednesday night. "When our defense plays the way it did today, it gives us a lot of confidence," Broncos coach Chris Petersen said after his team won its 16th straight home game. "Every defense wants to play like that. But these guys have really been backing it up."
