I had an interesting conversation about this very topic over the weekend. I should preface all of this by stating that I am a huge football fan, so in no way is this the ranting of someone with a strong biased against the game.
Basically, is football fatally flawed in its current format and given (some of) our expectations for the game? I'm talking about concussions. It seems like every year players are getting bigger, stronger, faster and more freakish, all things that widely increase the game's appeal. Who doesn't like watching a 6'3" 260lb linebacker who runs a 4.4 40 chasing down a bowling ball-shaped running back with the ability to stop, start, accelerate and change direction like an all-wheel drive Porsche?
But the human brain is incapable of better handling the huge, violent impacts that occur on a regular basis. As the league becomes more and more concerned with the severity of the brain damage suffered by its players, is there any way that football can last without changing the rules drastically to cut down on these injuries, and will these possible changes "water down" the game to the point where it loses its appeal to us?
Also, given that there are only 16 games and there are literally millions and millions of dollars riding on the outcome of each one, is this another fatal flaw? Is the increasing emphasis on getting every call right placing an undue importance on the performance of the referees in relation to the players' performance?
Would football be better off if it revised the rules about tackling to the point where the big-time collisions we love to see are eliminated? Would it be better if perhaps the season's schedule was changed so they played twice a week under these new rules and played 32, maybe even 40 games, a year so that there isn't such import placed on each and every possible game-changing call?
