Funny that you mentioned boxing in your analogy, since my friends and I were recently discussing the future of football as we know it and the concensus was that football is heading down that same downward road. Sure it may ten or more years in the future but when CTE cause and affect become more readily known, only the underprivlidged and poor kids will play the game. The tide will begin to turn when high school programs can no longer support and pay for the insurance premiums needed to protect them from injury lawsuits. This will eventually effect college and pro football in the number of participants willing to sacrifice their future quality of life, as well as the costs associated with defending against and paying injured players. Don't know what will replace football as Americas #1 sport, maybe lacrosse or soccer as we've been told for years or baseball might once again become #1, we will see.
