So what? That is just 1 metric. The main one is the D in reality held USC to 21 rather than 35 points.
A fumble. A late garbage time TD. Context matters.
I agree the D wasn't ideal. But given this was the last game of the season, a rivalry game, some jitters, an injury to the #1 RB...mission accomplished. And since you seem to like stats...ND beat USC by a bigger margin than anybody else this season.
Would modern era ND have dug this deep? Exemplified in a pick-6 by Gray, who up to that point had a torrid game. Grit. Nastiness. I dare say humility.
I saw an ND that punched them in the mouth, they punched back, but ND threw more and connected. I haven't seen this kind of season since the days of Holtz in terms of tenacity. They did not play great, but yet won decisively enough.
Finally, I agree we will see how ND does vs a stronger team. I remain wary even if optimistic. But that optimism is higher...because as I watch these other teams, none are that way above the rest. Ohio State lost to Michigan as an example.
ND has a shot. MF needs to clean up things. Work in progress, still one...thank God.
