That's a whole lot of faith in a system that just lost its entire brain trust and most of its elite talent. The scheme didn't make those players first-round picks, their freakish traits did. You can't just plug and play when you lose that much production. Michigan's defense last year was 2nd nationally in scoring defense at 10.4 points per game. Replicating that without Will Johnson, Mason Graham, and Kenneth Grant on the line is a fantasy. Their havoc creation and run defense were elite because of those individual disruptors. New faces learning assignments doesn't replace that raw power. Look at the schedule, they open with Texas. You think a "system" with new linebackers and a rebuilt secondary is containing Quinn Ewers? That's a brutal reality check waiting to happen. The third-down success you mentioned was a direct result of a pass rush that generated pressure with four guys. If that interior push regresses, which it will, the coverage gets exposed no matter how well they're coached. The floor isn't high when you're replacing coordinators and stars simultaneously. The structure might be sound, but the engine is gone. They'll be good, but top-five defense good? The data from EVERY major program after a mass exodus to the draft says that's a massive drop-off. LSU faced this last year after losing Boutte and others, and our offensive efficiency plummeted. Michigan's defensive efficiency will follow.
