This seems to be inaccurate. Black coach/white QB in Indy, Cincy, Pittsburgh, Oakland, Chicago, Tampa, Minn. White coach/Black QB in Philly, Carolina (Rivera is actually hispanic), Seattle. To the best of my recollection, the rest are White/White. I am sure I am missing something, but regardless, there seems to be no such trend as described here.
Now you know its campaign season and that means we have to keep the race card alive. Cue Business Insider.
I see the same thing. I think we can chalk this up to the MSM trying to create the news rather than report it.
