He was at that 1981 LSU game that I linked to below. Gerry had Devine speak to the team at a practice. As Devine observed in his book it was a smooth transition. Contrast that with the way people have become ex-Notre Dame head coaches in this century: by being fired for incompetence. Makes return appearances rather awkward.
Another return trip was in 1985 for the MSU game where he was honored at halftime for his hall of fame induction. Again, not something we're likely to see with those three recent goofs.
