The constant tweaking of rules and schedules has changed the game. All the engineering attempts at creating more passing and scoring have failed as every team now plays a base nickel D. This is why running QBs are so important now. Thursday games and overseas games always look inferior.
The final nail in the coffin will be the 18 game schedule. The human body just can't sustain that much collision. It will require a second starting quality QB.
The next crisis will be parents' refusal to enroll their kids in football because of injury. Do you see how early players retire now? Aaron Donald still in his prime walking away. Unheard of ten years ago.
I still love it but more for the fan experience and tailgating than for the game itself. You can see its demise coming with the greed ***** of gambling and private equity money. Someday tourists will visit the Ralph like we visit the coliseum in Rome.
