The 2011 defense ranked #36 in scoring defense and #28 in total defense. Last year, they returned 9 starters, but were #104 scoring, and #107 total defense (NCAA stats). While some injuries hurt, I think the main reason was changing to a complex 3-4 defense with coaches who could not properly coach them. I think this years defense will be closer to the 2011 defense, but I am more concerned about the offense. If they can reasonably come together, I think 6-6 or 7-5 are definitely achievable, with an outside shot at 8-4 if they can surprise someone.
