You guys biggest problem is assuming that there are good guys in the NFL/owners association. the whole league is about money. the owners are all about money. There is no integrity in this game, it is about who can make the biggest amount of cash. Winning obviously helps that. These are billionaire team owners. Every single one of them has stepped on people to get where they are. they managed loopholes and probably did some shady shit along the way. You do not make that kind of money without making enemies.
Stadiums on the outskirts in the suburbs might be on cheap land, but there is a reason that land is cheap. Nobody wants to be there.
Look Im not saying New Orleans is a high class city. Its really a fucking dump. I visit it fairly frequently. But its also a great place to hold big events and parties from years of experience with high amounts of tourism and a history of successful past events. Its extremely good at hosting things like the super Bowl and thats why the NFL likes it. If it was such a bad place to hold one then why have their been 10 of them there? There is a reason for all that and it has nothing to do with "Katrina". It is designed in such a way that massive amounts of people can move from one staging area to the next with relative ease and party the entire time. I can see why Goodell wants a european city to host big events in the future because the logistics in the cities work out much better (aside from getting people overseas to begin with).
