That's because Trev lived it. Nebraska always talks about hiring "within the family."
Think about this for a minute: The last time we had "Husker Family members" at BOTH the AD and HC positions is when they promoted these two guys.
We've had
four former players/coaches take on the Head Coach or Athletic Director position: Solich and Frost (HC), and Devaney and Osborne (AD). If you want to get technical, Dave Rimington was an interim AD for a period, and Pelini "returned" as Head Coach, although he only coached a single season as Frank's DC. I'm not sure if a single year as an Assistant Coach makes him a "returning" Husker or not. Better ask Bob Diaco if he feels like a Husker.
Anyway, you can argue that Osborne was the AD who hired back Pelini, and I'll give you half-credit for that answer. But we've
never had two former players occupying both those roles. And never had any player/coach combo with any "significant Husker tenure" since Devaney & Osborne.
