Duke D taking care of Navy

Somehow, Duke's defense is stifling Navy and quarterback Ricky Dobbs as the Blue Devils lead 17-0 in the second quarter.

Duke quarterback Sean Renfree has completed all 11 of his passes for 128 yards and no interceptions. The Blue Devils are controlling the clock, winning the turnover battle, and playing disciplined defense -- on the road. It's the perfect formula for beating Navy. We'll see if they can keep it up.
