I've heard the pros and cons from various parties. I know there's a lot at stake here. One of the key issues is that people just aren't turning out for the preseason games. While they may have to buy the tickets as a part of the season ticket package, its clear that they're still not showing up which means less revenue from concessions, parking, number of eyeballs seeing all the in-stadium ads, and the like. So, Goodell correctly assess that "the fans have spoken" and that would be with their wallets.
The owners want to make more money and are in favor of expanding the number of games. The players realize it means more wear and tear on them.
And interestingly, Goodell has said he won't start the NFL season before labor day; and the only logical conclusion is that the SuperBowl would have to be around President's Day Weekend (mid Feb) - an idea I heard from one NFL executive.
So, here's what I would consider:
* Expand the roster of players to at least 65 players, thus making up for more wear and tear
* Change the injury rules to be more like baseball's DL, where a player is unavailable for a finite amount of time, with limits. So maybe you can have one player who can miss 4 weeks; two can miss 6 weeks, and 4 can miss 8 weeks. And in the time they're inactive, you can sign someone to take the roster spot.
* Give each team two byes, so the schedule is 20 weeks. Spread them in a way, so that maybe half the teams get week 7 & 14, and the others get weeks 6 & 13, so there's no clear advantage to anyone and you have football every week.
And here's where I think things get interesting. You have your two "scrimmages" (a/k/a preseason games) to tune up the team. But the first two games of the season can be used to do some evaluation as well. You allow for a larger roster with a cutdown before week 3. Teams might want to play some of these guys in the games, and I would wager that some coaches might develop a strategy to play more of the younger guys in these first couple of games to prevent injuries. The games still count, but coaches have to make smart choices about how deep to play some players with an eye on winning. And if they did play some of their vets later, it may cost them later in the season.
That's my two cents. It would make for a better product, certainly.
