It's such a BS narrative.
The only "home run hires" of the past 2 decades have been Saban at Bama, Urban Meyer at Ohio State, and Jim Harbaugh at Michigan; and the last of those "home run hires" hasn't even totally worked out.
All the other great coaches hired were considered disappointing by a large portion of the fanbase:
Pete Carroll at USC
Dabo Swinney at Clemson
Mark Richt at Georgia
Bob Stoops at Oklahoma
Matt Campbell at Iowa State
Mike Gundy at OK State
Mack Brown at UNC
Kirby Smart at Georgia
All considered risky or even outright bad hires. The Pete Carroll and Dabo Swinney hires, in particular, were trashed mercilessly, before turning out to be 2 of the best college coaches of the 21st Century.
There aren't a whole lot of "home run hires" out there and they are rarely available even for the top jobs.
