The owner will make up any lose revenue because of lost ticket sales at the superdome with ticket sales at Wembley. The NO economy won't.
The hotel that houses the media, the SD chargers team and its fans won't be sending a cut to the hotel that would have housed them.
Nor the local restaurants or bars.
The parking lot down the street that will not have a game day parking special 3 times its normal daily rate, won't make up the lost revenue. The parking attends that would have worked that day won't be getting paid.
The guys and gals who sell t-shirts, peanuts, game programs, beer and assorted other stuff outside the stadium will lose 1/8 their business for the year.
The employees who clean the bathrooms, sell the beer, and take tickets on game day won't be getting their game check, even thought the players will.
Nor will Charger fans return to SD with stories of how much fun they had NO, prompting others to be tourists for completely non-football related reasons.
The owners of the Saints won't take a hit, but the wrong city will.
No, the NFL choose the wrong city to hit with a huge economic lose.
