Wisconsin has now completely gone away from the “bunch the box and run over teams” offense. And they weren’t exactly playing in the SEC. Imagine trying to make that against actual Top 15 recruiting classes on a yearly basis? Will Muschamp went through 2 SEC jobs trying to figure that out.
I've seen them start to transition into a more wide open offense in recently. But, during the 90's, the SEC was not necessarily king. The B10 and the B12/8 were the top conferences. I remember PSU recruiting top 5/10 classes routinely in that era, loaded with NFL defensive picks and they still couldn't stop Wisky running the ball. Wisky never recruited like OSU, Michigan, or PSU during that time. I'd venture to say that even MSU recruited better under Saban in the late 90's when they were getting Parade All Americans. Yet, Wisky kept winning.
And I don’t think your academies example is entirely correct.
The academies do structure their style of play around shortening the game and not getting into a track meet.
They do want to shorten the game for sure. But, most of that is because of the inability to stop people.
And some of that is because of their defenses. But it’s also because of their offenses. They realize they can’t score at will either.
I can't speak for Air Foce, but being around the Army/Navy staff too many times to count, they believe(d) that scoring wasn't an issue. Army/Navy were extremely comfortable in 1 to 2 score games. When they got down by more then 2 scores, the game was pretty much out of hand because the defense couldn't get stops and teams took the air out of the ball.
Now, to your point, that could be an offensive athlete problem too.
There is some truth to that as well. The playbook can't be extensive offensively because most of these guys are PSAC/FCS type players.
It should be noted that the service academies are changing their offenses as well. Army is going to a completely shotgun offense. Navy is going to start phasing it in and will probably be completely shotgun soon.
Monken is coaching for his next job. He knows 99% of the power 5's will not run the triple option from under center. You saw what happened with Kenny Niuamatolo when he was basically offered the AZ job but the QB protested.
Newberry at Navy is truly experimenting this year. His leash won't be very long at Navy if he doesn't do what Kenny did in terms of success. If they struggle on offense, which they will, he will be back to under center.
Calhoun is the only academy coach who has been 100% under center for 2.5 years straight. It shouldn't be a shocker they've been by far the best academy in that time.
Army experimented with the run/shoot at times in the past 30 years. They were terrible. As soon as they hired Monken and went exclusively under center - they became relevant. Navy was in the same boat prior to hiring Paul Johnson.
