Football

it's pretty much an open secret--hell, it's not even a secret anymore, is it?--that teams bring in nonwhite candidates merely to fulfill the requirements of the Rooney rule despite the fact that they've already settled on a white candidate or narrowed it down to one of several white candidates, often white candidates who've already had dismal or mediocre careers as HC already (although we're getting fewer retreads recently as teams move toward hiring younger HCs).

At any rate, none of this has anything to do with the nepotism problem in the NFL and the ways it harms diversification of coaches.
