Relying on talent and disruption is a high-variance strategy both game to game and year over year.
No scheme has the answers to everything but how you choose to fit runs (including fronts and alignment) and how you defend space in the pass game (including safety looks) determines what an offense can and cannot attack. People like
@Coach Macho complain about Diaz's scheme because it's unsound.
Now that doesn't mean it can't work. If Miami's front improves to where they aren't getting gashed by the run and they play more 2-deep man coverage with big physical press corners it could be an elite defense. But again that's entirely dependent on talent transcending and I still have major doubts about them stopping an RPO superspread offense with diverse run concepts like UNC.
