Sometimes I wonder if Frost would have been more successful at a school other than Nebraska. I think the idea of "Husker Power' poisoned his offense.
Well, he
was much more successful at a different school, and that school was UCF (even if it was a lucky flash in the pan). And I don't even know how we'd draw any straight lines to "Husker Power" and what he was doing as a composite of all 4.25 of his years here.
A lot of today's popular offenses were developed for this reason; to overcome offensive line talent disadvantages. The spread to run offense Frost used as a base is one of them. It's designed to run against light boxes and to use pulling linemen to create numbers advantages.
As the stats show, in years 1-3 we at least ranked in the top 30 nationally in rushing yards per game. And Jurgens pulled a lot, and was extremely good at it, and some of that scheme was actually fairly successful here. But by the 2021 season, the offense as a whole was just fraught with unforced errors; there'd be false starts, turnovers, and even away-from-the-ball 15 yards penalties that would kill drives.
And as I mentioned in a part of that post that you didn't quote above (which is fine, there's no "tone" in what I'm saying here

), years 3 & 4 maybe didn't have as much outside/over the top talent as years 1 & 2 did. We did have Betts in year 4, but it wasn't enough.
So if the theory is that B1G defense are still big, strong, and lean more towards playing the box, what Frost was trying to do wasn't a bad idea. The scheme itself was in my opinion excellent not only in and of itself but also excellent for the B1G.
But a huge problem by years 4 & 5 were fairly bad issues with blocking in both the run and the pass, and then also tremendously bad issues with unforced errors.
