NU's run defense has degraded every year since 2009, ans so has scoring defense. Is this a trend? In 2010 mobile QBs were Bo's nemesis. Now some teams run at will on NU. Have opposing OCs figured out how to beat Bo's defenses. My opinion is that Bo puts more emphasis on stopping the pass than the run and other teams have figured this out. Unless NU changes schemes or is loaded with NFL caliber interior lineman opposing teams will continue to exploit the weakness in the scheme, run the ball and control the clock. Below are some stats I pulled. These are national ranks. Scoring, Total Yards, Rushing Yards, Passing Efficiency 2012 - 56, 22, 96, 2 2011 - 39, 36, 66, 25 2010 - 8, 10, 52, 5 2009 - 2, 9, 11, 3
