Football is dying in suburbia. White kids play lacrosse, etc. now. It’s becoming a sport played by poor white and black kids. Asians and Hispanics have little interest in the game and those folks are an ever increasing piece of the demographic pie. While the NFL won’t go away it’s best days are definitely past.
I became a fan at an early age because my father always had the games on at the house when growing up and it was one of few things we had a bond with. Also, at school, my classmates would always be discussing the games come Monday. When my own sons were growing up, I also had football on in the house but my sons would rather be on their computers and other devices. They had no interest in football at all and neither did their peers. Different world.
