Or even Wisconsin basketball from almost a decade ago. A bunch of kids in a program who played in a system and nearly won a national title. Football is a tad different but playing within a system matters.
When Michigan State was really good, back when Narduzzi was the DC and Tressel the LB coach (2013 range), they applied this model. They ran that stout 4-3 quarters coverage, which is tough to implement well because you rely on being really good at your reads, especially in the defensive backfield. They started a lot of juniors and seniors who "paid their dues" learning in a system. Unsure if this is possible any longer as kids can now bounce if they are not playing right away.
