Notre Dame has a number of key questions it must answer on the defensive side of the football. Who replaces Jaylon Smith, Sheldon Day, Romeo Okwara and the other departed seniors? Where will the leadership come from after losing four defensive captains? Will defensive coordinator Brian VanGorder be able to strike the right notes to get the 2016 defense up to speed? Blue & Gold Illustrated senior editor Lou Somogyi and football analyst Bryan Driskell address those questions and much more in the latest edition of the Irish Huddle. Subscriber questions concerning the defense are also addressed.
