Mindless expansion is pretty shortsighted IMO. Of course if there are more teams there is more turnstile money. But the league is so compelling right now, TV dollars enter the mix, and I think keeping the league compelling should be the number one goal, always. Adding a couple more games, screwing around with international teams, expanding to have too many teams, those are small-minded things that yeah mean more short term dollars. But you make a mistake with that stuff and you can end up the NBA or MLB much faster than you think. Especially when you're also messing with the hard hits that are so much a part of football.
I keep waiting for a commissioner to have the brains to shrink the league down to 28 so all the teams are loaded with talent. That, plus the parity that already exists in the NFL, would make the games so compelling people's minds might explode.
That won't happen though. He does the bidding of the owners, and the owners aren't going to live forever. Diluting the talent in the league isn't going to harm it in their lifetime, so it makes perfect sense for them and by extension Goodell, to pursue options that aren't in the long-term best interests of the league.
