Duke with an extra week to prepare always plays the option well. Army is off a huge win over Air Force 21-0 where they did not have to attempt a pass. Army really only cares about their last game of the season now when they face Navy having already accepted their bowl invitation to the Armed Forces Bowl in Fort Worth.
Duke is used to defending the triple option as they play Georgia Tech yearly. They held Army, a talented offense last year to just 6 points and 3 points in 2015. Since Jim Knowles took over as defensive coordinator, Duke is 9-3 ATS vs. Army/Navy/Georgia Tech, all three run the triple option. This year's Duke defense is better than last year's against the run. Only two opponents have ran for more than 4 yards per carry on Duke this year, but they find themselves coming off 5 straight losses. This is a big game for them with Georgia Tech and Wake Forest on deck they'll need 2 wins in their last 3 games. I trust David Cutcliffe will have a great plan off the bye especially offensively where they have scored 2TD's more than their season average off the bye. It's worth noting that Army is ranked 115th in yards per play allowed. Duke has faced 4 top 35 defenses over their 5 game losing streak.
