I agree with your take. I won't budge an inch on that 1973 championship. It's legit as any other. I'm just saying if you consider how the parameters changed, it's one that worked out in a fortunate way for us due to the times.Well, I'm sorta willing to concede we "got away with one" in 1973 save for the fact we won it WITHIN THE RULES. Sure, they were stupid rules, but so was the time when Notre Dame got one knowing the bowl games wouldn't count and played for a tie.
The issue with the BCS was always when there was a potential "third team." The CFP removes that one issue. If you're number five, you're out. The end.
