I agree with you...but ummm...you are assuming the NFL wants these coordinators to figure out how to utilize black QB's...
The NFL has deliberately tampered with the game so that black QB do not flourish.
..and non athletic stiffs like Brady and Manning can sit in the pocket and throw for 500 yards any time they wish...
They have made the running back irrelevant under the guise of "the game moving in a different direction"...
Corner Backs, Middle LB's and Free Safetys are hampered by the touchy calls under the guise of new defensive rules
and Wide outs are treated like stepchildren...as slot receivers become the focal point for these new type offenses
Most of these positions were dominated by men of color...and usually men with big personalities....
replaced by stiff white dudes who do it the right way
With that being said....I ain't watched a game this year and do not plan to regardless....
