It probably should fall more towards the level of college players. That's a huge pool of people than are essentially starting their careers years earlier. I personally would prefer someone with a degree who had enough self awareness that they weren't going to play as a pro and took the initiative to at least get that piece of paper during that time. Their biggest hurdle is getting an invite to the big dance as a position coach.My expectation is that if there isn't bias involved, then I'd expect the diversity of coaches to fall somewhere in between that of college and the NFL players which I think combined is the main pool of potential candidates.
Which does lower the minority percentage from that of the NFL players alone. We saw those stats back in the Rooney Rule's early days though I don't recall the exact numbers, but it was closer to 50/50 than 75/25 as the NFL is. But even expecting a level in between college and NFL ratios, where the NFL was, and still is, is so far away from that, that it's pretty tough to believe there isn't bias at hand.
I do think NFL players have a leg up on college players for more exposure to the sport and higher levels of coaching to interact with, and more contacts with decision makers. But it's true that NFL players isn't the exclusive pool from which coaches are drawn. However, the general US diversity makeup is a horrible level to cite.
All that said, I don't have a specific reason to think bias a deciding role with Bieniemy. I'm sure it was there as much as it is with anyone, but I don't think it would be the trump card in his case.
Because of the high regard for his coaching there was, I would have expected that to be enough to trump bias with some team. But then we do hear of the other issues he has and that seems likely the main issue with him. When his last head coach had to publicly address how he had to smooth over a rift between the players and EB, that's pretty telling.
