I don't think you guys paid ANY ATTENTION to this article. At all.
Boxing used to be as much if not much more popular on a percentage basis than Football. Other than the Super Bowl, big fights would shut the country down as they were on the radio and Friday night was "fight night" all across the country.
The point is that things CAN change. Heck, in the 20s through the 70s, baseball was the predominant sport. Basketball became the most popular sport by the mid 80s and 90s, then football took over.
The NFL's current dominance is by no means guaranteed. It's a relatively new phenomenon and the sheer VOLUME of things that are building that could drive groups of people away is growing. Will it drive hardcore fans away? No. Then again, hardcore fight fans never left boxing, baseball or basketball, either. It's the fringe, casual and other groups that coalesce around a sport that are tributaries into a confluence that becomes a mighty river of momentum that is a popular domination of popular culture and consciousness.
When those tributaries dry up, the mighty river ain't a river any more. It's a shallow river and in places a glorified creek.
It's never been all about the hardcore fan. If it were, no commissioner would ever try to appeal to any fan beyond the hardcore. The money is in all the rest of the fans who exponentially outnumber the hardcore fans, usually 5 or 10 to 1.
If the NFL loses the non-hardcore fans, the current financial model of the NFL completely collapses. The sponsors will bail because they follow the fans and the behavior of NFL players (or more accurately, the public's willingness to tolerate the bad behavior) has gotten so out of control that these fans find this avocation to be an untenable way to spend their time and money, especially if it violates their personal principles.
Is the NFL in that spot now? Only at the very fringes..., but the problem is that people are asking this question, "is it moral to be a fan of the NFL" in major, mainstream publications and the answers aren't straightforward.
That's a MASSIVE problem for the NFL because only a few years ago, such a question would have been laughable, even though there would have been plenty of evidence that such a question were legitimate (we all know the domestic violence problem with the NFL has been running amok for ages, for example, and there are legions of examples of Domestic assaults being essentially unpunished by the league). Well, it's not laughable, anymore.
As dedicated fans, we are different. We spend TIME on a specific team and the NFL in general. We're likely to take the NFL, worts and all for quite awhile. It would take a lot for many of us to walk away.
But that's not what the article said. And it's important for us to take note of that. Because just like we pay attention to salary caps and all that... if this becomes the year of a "fan awakening" where fans are just inundated with player misconduct stories from Ray Rice to Ray McDonald to Greg Hardy to Adrian Peterson and the list just keeps growing each week and bouncing from "breaking news" to "breaking news"... non-dedicated fans will leave and the sponsors trying to reach THOSE fans will leave also. And that will affect the bottom line of the NFL in ways we can't predict.
The one thing that's NOT going to happen is that the press isn't going to stop looking for these stories now because they generate clicks and they are of interest.
If the NFL and the various teams don't get out in front of this, this problem will create its own solutions and they won't be good for the NFL.
