Joe Montana was absolutely great at Notre Dame, and his comebacks were second to none, but his even greater pro achievements have if anything inflated the well-deserved legend of his ND career.
Joe Theismann was awesome here. Hard as it is to pick, I'd choose Theismann's ND body of work over Montana's. He stepped in at midseason as a sophomore (no freshman eligibility then) for injured senior Terry Hanratty, AHEAD of excellent senior backup Coley O'Brien, and the team didn't miss a beat. In 1970, he carried an otherwise ordinary ND offense to damn near an NC season. As Ara said, "Never overlook the magic of Joe Theismann."
