Looking at the S&P+ ST rankings, ND is 56 which is better than Alabama at 92 and Clemson at 67. And to put a fine point on it, Alabama with a 92 ranking in ST played LSU with a ranking of 3 last night. How much difference did ST make?
If you look at the top 10 teams by ST rank, they are a combined 47-32. Again, it doesn't matter that much.
