Well here's a snippet...
most people view '95 UNL as THE team. So let's look at one aspect of '95 UNL vs '19 LSU:
Nebraska's pass defense was good that year, but not special. Nor did they have an inordinate number of sacks. However, we all saw how they did vs Spurrier's offense in the Fiesta Bowl. They had time to prepare and Florida had a rudimentary pass-blocking scheme.
I think UNL's pass defense/pass rush is inflated in our minds because of that game. Kudos to them for displaying their peak defense vs the passing game in the biggest game of the season, but their baseline or average wasn't special. Does LSU have more 3-step drops than Florida did? Burrow is 100x more agile in the pocket and scrambling than Wuerffel was. Stronger arm, too. Idk if LSU's OL is better, but their scheme certainly is.
I don't see a repeat of UNL's pass game defense vs '19 LSU. They were very good, I'm not talking down on them. But I've spent the past 5 months of my life familiarizing myself with individual teams from the past 50 years and that wasn't a team strength.

That's the sort of thought experiment that works with comparing teams across eras.
