I never liked Kelly’s offense, and I think for most of his tenure the defense has carried this team.
It’s true for the past few seasons though ND’s best overall one year performance was on offense in 2015.
—4 seasons in which defense was the strength of the team: 2019, 2018, 2012, 2010
—2 seasons (or 3) in which offense was the strength of the team: 2015, 2014, (2013)
—1 season in which both were strengths: 2017 (though 2018 could be applicable here)
—3 seasons in which neither was really a strength: 2016, 2013, 2011
Offensive and defensive efficiences under Kelly. Team efficiencies are based on the point contributions of each unit to the team's scoring margin, on a per-play basis. The values are adjusted for strength of schedule and down-weighted for "garbage time.”
2019: 26th in off efficiency, 5th in defensive efficiency—defense was clearly the strength of this team
2018: 19th in offense, 11th in defense—defense was the strength of the team
2017: 12th in offense, 10th in defense—both offense and defense were strengths
2016: 45 in offense, 46th in defense—neither the offense nor the defense was a strength
2015: 3rd on offense, 61st in defense—offense was clearly the strength of the team
2014: 22nd in offense, 61st in defense—offense was the strength of the team
2013: 33rd in offense, 49th in defense—offense was the strength of the team though it wasn’t that good
2012: 25th in offense, 10th in defense—defense was clearly the strength of the team
2011: 28th in offense, 23rd in defense—defense was slightly better, neither “carried” the team
2010: 63rd in offense, 19th in defense—defense was clearly the strength of the team.
