SOUTH BEND, Ind. — Notre Dame coach Brian Kelly fired defensive coordinator Brian VanGorder on Sunday, hours after an embarrassing 38-35 home loss to Duke dropped the Fighting Irish — who started the season ranked No. 10 — to 1-3. “I had time last night to evaluate our current situation and made what I felt to be the best decision for the program,” Kelly said. Greg Hudson, a former Irish linebacker under Lou Holtz who was hired as a defensive analyst over the summer, was named VanGorder’s replacement.
