VIDEO: ESPN's Mina Kimes Drops Truth Bombs About Lack of Diversity Among NFL Head Coaches

The NFL's "Rooney Rule," which requires teams with coaching vacancies to interview at least one minority candidate, has not served its intended purpose. In fact, in recent years, the proportion of non-white head coaches around the league has actually gone down, with Chiefs offensive coordinator Eric Bieniemy being the most recent high-profile assistant to be denied an offer for a top job this offseason. ESPN's Mina Kimes noticed, and went off on this troubling dynamic on "Outside the Lines."

She could have let loose a lot more ruthlessly than she did, too.

Kimes points to nepotism and a general bias toward familiarity as key culprits here. It's easy to get the inside track on a coaching future if your father is or was a coach -- just look at Mike Zimmer and Gary Kubiak and Norv Turner, whose sons are quite possibly already on a head coaching track. Hell, Bill Belichick and Wade Phillips and the Ryan brothers are all the sons of coaches.

White coaches.

There's no way to break through and realize a new wave of diversity among the NFL coaching ranks in needed unless owners -- white owners, for the people in the back! -- decide on their own accord that change is necessary. Short of that, a strong and spirited reconfiguration of the Rooney Rule could be the only thing to keep talented minds like Eric Bieniemy from being passed over after the most cursory of looks.
