The more I see what's happening, the more I'm convinced the NFL is completely out of touch and not operating like a true business would. First, they're a monopoly backed by the courts. If they employees of a small business acted this way (with the consent of their employer), they'd be completely out of business the next day. But the way the NFL is set up, they generate TV revenues and revenues from their stadium deals so I'm not sure how much this hurts them financially. Heck, season ticket holders are stuck with the product and these owners know it.
The NFL has completely lost touch with their rabid fan base. This has been happening for some time, as they would rather attract big business to their stadiums using expensive seat licenses than the working man who might want to take his family to a ball game. They've almost priced these folks right out of their market. To top it off, the new stadiums are financed, in part, by the same tax payers who are getting priced out of the game.
Lastly, I was kind of surprised how much play these protest were getting by the stations broadcasting the games. And then I thought, why wouldn't they? It's to their benefit to highlight these protests, as it will only help them when the next TV contract comes up for renegotiation. How much more money can the NFL ask for when viewership is down across the board?
