No. Division 1A (aka, FBS) football teams have not played D-2 football teams in several decades; however, most Division 1A teams now host one game against a team from D-1AA (aka, FCS). Some 1A teams even host two 1AA teams in a season, such as last year when Florida State hosted Western Carolina and Chattanooga. Do not confuse Division 2 with Division 1AA. Keep in mind that D-1A football teams are simply D-1 for all sports other than football, while D-2 teams are D-2 for everything. For example, D-1A football schools like Villanova, Georgetown, and Davidson have basketball teams who compete for the D-1 national championship. Notre Dame has not played a team from D-1AA (FCS) since D-1AA came into existence in 1979. Appalachian State has no agreement whatsoever to play Notre Dame in football at any time in the future, but ASU does have contracts to play at East Carolina, Georgia, Virginia Tech, and Florida over the next several years.
