AP poll in five seasons. Holtz retired from Notre Dame following the 1996 season, but would unretire in 1999 to accept the head coaching position at South Carolina where he would serve until the completion of the 2004 season. Bob Davie (1997–2001) Bob Davie, who had been Holtz's defensive coordinator from 1994 to 1996, was promoted to head coach when Holtz retired. Davie, who turned down a head coaching offer from Purdue to accept the Irish's head coaching position, was a well-respected defensive mind who had also served as defensive coordinator at Tulane and Texas A&M. Davie had also filled in as head coach for one game during the 1995 season when Lou Holtz was dealing with a health issue. One of his first major decisions was to fire long-time offensive line coach Joe Moore, who then successfully sued the university for age discrimination.

The aforementioned 2001 Fiesta Bowl was Notre Dame's first invitation to the Bowl Championship Series.
