The current model hasn't been done by Goodell. Regional games have been televised forever, regionally. Bigger games have been televised outside of their region for a lot longer than Goodell. Sunday night/Monday nigh games have switched. Sure you can watch a lot more NFL network, but that's new, and an add on. Not something they took away from people. all of those games on there weren't available to people all over the country before the NFL network.
and considering how much the NFL has increased in popularity under Goodell, i'm sure it's going to take more than 1 season to get him canned. it couldn't continue on it's current course forever. Nothing can. There's always expansion and contraction and ebbs and flows. just stick with something long enough, you'll see, it's not always up just as it's not always down.
My guess is there is so much more at play than just Goodell, and those that say they aren't watching until he's gone either aren't going to watch anyway, or already are watching and just telling you they aren't so they feel better about themselves for some reason. For the spakling of fans that may actually be boycotting, well they probably aren't enough to matter. The NFL has become it's own worst enemy IMO and it's not just because of Goodell. They've catered too much to the casual fan. WHich was great for ratings boosts and increased money. But casual fans are casual. They'll turn their attention as soon as new winds blow. They better make sure they don't turn off their base or there will be nothing left to support them eventually. That scenario is pretty far off, but it's still a possibility.
They've invited in the opinions of all these people by appealing to everyone. Some good, some not so good. now the game and how it's presented will change according to what the masses, the new masses are demanding. Owners are going to look at how Goodell adapts to these changes and judge him on that. a blip in ratings isn't going to do it. a poor or non reaction in response to getting people back interested in competitive games will though, eventually.
