I'm honestly conflicted on these types of things. We've been through the phase where they kind of forced folks to hire the Tony Dungy's, Marvin Lewis's, and Mike Tomlin's of the world, and it's probably not right to continue forcing it at this point. When someone owns a company, business or team, they really do have the right to hire whomever they want or FEEL is best for the job.
Unfortunately, this pretty much ensures that there will be an uneven playing field, and again, unfortunately, that's just kind of how life works. You could have two people with identical resumes, accomplishments and abilities, but human being are just imperfect, and most will FEEL more comfortable hiring someone from the same cultural, philosophical and ostensible background as them. I just really don't know how to fix this without forcing someone to hire someone they don't want, (and that's just not right, and leads to other nasty ramifications down the line).
