Rocket's freshmen season, ND was undefeated.
Sophomore season they lost only to National Champ Miami
Junior season they lost 3 games: 1 to Stanford in a game Rocket didn't play in (nobody to this day knows why), 1 to Penn St in a game they were winning when Rocket got hurt in the first half, then lost when he didn't return; and 1 to Colorado (the phantom clip).
With Rocket on the field ND basically beat everyone they played except No. 1 Miami in 89.
