This might not be a popular opinion with a lot of people, but I think it's a good rule. Doesn't mean you have to hire a minority candidate for HC or GM, but it means you have to interview a minority candidate.
I was going to write a long post on my thoughts on the Rooney Rule, which I support, but this article does a better job than I could. Oh, and it talks about Jerry Gray.
NFL's Rooney Rule has boosted minority coaches and general managers - Tampa Bay Times
The best illustration of the success of this rule, in my opinion, is displayed by this quote:
There hadn't been an AA coach to ever coach in the Super Bowl before the RR, and now look...I'm not saying the NFL was racist before. I'm just saying that it was stuck in a pattern of institutional groupthink.
Anyway, I'm sure there will be quite a few that disagree with me, but that's fine.
