It leads to a related question that interests me. I wonder how some of our old defenses which were elite for their time would look in today's game. Our 2003 team allowed 67 rush ypg--good even for that time--but they didn't live in a world of RPO's. iirc--and I might not--I don't think QBs in general were nearly as mobile back then, or if they were, it wasn't such a baked-in part of their offense. For LSU, every year's defense had it's own flavor in those days, but the evolution could maybe be benchmarked as follows: 2003 was the culture change, where everyone played with their hair on fire all game. 2007 (when healthy) was built to stop the more traditional offenses we saw at that time, but struggled with the incoming spread-option Urban Meyer was introducing to the conference. 2011 was the culmination of Chavis' answer to that, built to choke spread-option teams. 2016 was still in that mold, but more geared to combat the emerging RPO trend.
There's just a lot of firepower in offenses today, and the QBs on average, imo, have improved significantly in the college game over the last 20 years. Those old defenses I mentioned were great, along with several Florida, USC, Oklahoma, etc. defenses we could talk about. I still think an offense like LSU's 2019 or 2023 squad would hit 30+ on them, no matter how miserable the defense made them and how hard they would've had to work for it. I'm not sure LSU should expect a defense with that kind of production anymore, even if the talent were comparable. Alabama routinely fields offenses that are just going to score, no matter what defense is out there. That UGA team we ran into in ATL in 2022 had two TEs that were matchup nightmares and a scheme that made the defense wrong no matter how they chose to defend a play.
Predictably, the crux of our best defenses was the line, particularly the 2003 team. The reason why no plays worked on that team is because every play was dead before it started. I don't know that you can live off that anymore. The best O-lines are much more impressive than they used to be, I think, and they give crazy-good QBs and receivers enough time to run a play.
It's interesting to think about, but my hunch is none of those defenses I remember fondly would look as good now as they did then. Who knows.
