No kidding, but I'm talking about the ability of a team to make money or lack therof to justify a move which is what this conversation was about. And two owners are fighting for LA out of self defense, not because they really want to move.
I think Spanos wants to move, if he didn't he would make something happen in San Diego. Similar to Kroenke and St Louis, if either of those two owners truly wanted to stay in their city they would figure it out. I don't buy that a team in LA kills the Chargers, two teams could be tricky, but not one. Spanos' being willing to alienate 75% of his fanbase in order to keep 25% is stupid, he wants LA because he'll make more money there. Davis is probably the only one who really wants to stay but probably can't get a deal anyway. However there are other options than LA if the case was simply he needs something that works in general.
In terms of the ability to make money, there's so many reasons why it might work in one small area and not another. Take Green Bay for example, one of the reason's why it works so well, other than the history of the team, is because there's really just nothing else to do. If the appetite for football in one small city is large enough it can work, but if the city has other attractions or other teams, it obviously takes away from potential NFL revenue. If the city is large enough (New York, or Los Angeles for example) then they can afford to take the hits from other attractions because there are so many people they still have plenty to draw from. In a city like Jacksonville, where the county population is only 885,000 having all those different attractions means that the Jaguars are going to have trouble filling their seats, there's only so much to go around. LA county has 10.2 million people in it, they can take the hit.
The Jaguars need to attract about 7.5% of their county population to fill their stadium.
In LA they would need to attract .0008% of the population to fill the Inglewood stadium.
That's where big cities have their advantage. And that's why smaller cities with less to do are able to manage, while others who have more to do have issues. St Louis is home to world class teams like the Cardinals, that makes it harder for the Rams. Even if the Rams are doing well, they're still the #2 ranked team. What happens if soccer comes into town as discussed, then it's even harder for the Rams. Those are potential situations the NFL will need to look at.
