The NFL has been committing slow suicide for several years........this is all their own fault.
When I was going to college in the 70s, I worked at a Sears appliance repair center. I remember one year the motivational theme was "Sears Excellence League," with a logo that was a take-off of the NFL logo (I can't find an image of it on the internet).
The reason I mention this is that I see the slow demise of the NFL following in the footsteps of the slow demise of Sears, with the leadership either not knowing or not caring about its customer base or its target market.
