George Seifert — Montana-to-Young luxury made the résumé glow
The case
A strong
Best evidence
Seifert's record is spectacular, but his NFL legacy is inseparable from coaching a 49ers machine that moved from Joe Montana to Steve Young and was already the league's gold standard.
Mike McCarthy — the Aaron Rodgers title window still does most of the reputation work
The case
Best fit for the prompt: one legendary quarterback and one ring still shape a reputation that playoff results keep challenging.
Best evidence
McCarthy has a Super Bowl ring and a strong regular-season résumé, but the argument against him is that one 2010 Packers run with Aaron Rodgers still outweighs years of playoff underperformance in Green Bay and Dallas.
Sean Payton — the Drew Brees halo remains enormous
The case
A clear quarterback-dependent legacy case, though Payton's scheme influence keeps him from being ranked as a pure passenger.

Best evidence
Shanahan's résumé is heavily anchored by back-to-back Super Bowls with John Elway, while his post-Elway record was far more mixed despite his lasting offensive influence.

Best evidence
Gruden's reputation as a quarterback whisperer and program-builder still leans heavily on the 2002 Buccaneers Super Bowl, even though that team's identity was its historically great defense.
Brian Billick — one historic Ravens defense still defines the brand
The case
Included because the
Best evidence
Billick arrived with an offensive-guru reputation, but his coaching legacy is still mostly the 2000 Ravens' Super Bowl season, powered by one of the greatest defenses ever rather than quarterback brilliance.
