I would imagine you have to at least put a modicum of effort into it, rather than calling Herm up and asking how the weather is.
Even an hour interview for the minority candidates that would otherwise get nothing helps. Do you have any documented cases where the team that wanted the superstar coach the most didn't get him because they were waiting to interview a Rooney rule candidate first? Every team has to do it, so it's not like this rule benefits certain teams without a coach more than any other team without a coach.
Do you ever actually address the people that these complaints are referring to or do you just post passive-aggressive whines aimed at no one in particular?
