Looking at one year in isolation as a baseline is misguided. You have to look at all 32 coaching jobs and realize it’s not a this year issue but an accumulative issue.
secondly, without going to far into it, the Kapernick settlements shows the nfl and owners are more concerned with along money not winning, as the two are not correlated. In the vein of making money the nfl will put political/racial issues over winning.
Thirdly, the nfl is moving to hiring offensive minded coaches that former QBs, there’s not many minority candidates with that background due to the history around the position.
Lastly, I would say Eric Bienemy and Byron Leftwitch come to mind as minority coaching candidates that I would higher over Rhule, zac Taylor, and the Pats wr coach hired for the giants, yet they didn’t get interviews. So yes it should be about looking purely at qualifications, but unfortunately it’s not and the Rooney rule is here to give qualified minorities a chance. Looking at how many coaches are fired yearly and how many teams underperform, clearly the best coaching candidates are not being hired.
