Come on guys, you must be kidding. The NFL is about as valuable a franchise there is in the business world. A few teams are even reportedly worth a billion dollars now. Yeah more legalized gambling might have increased the ratings a tad, but come on does anyone really think that many people who would want to gamble on the games aren't already doing so? This isn't like poker, just waiting to be discovered.
As for the rest, Tags isn't exactly a miracle worker. The Commish is really just an employee for the owners in most cases. He couldn't have done much more on the rules, that needs pretty universal agreement with the owners. The LA franchise is just a fact of life; LA doesn't want a team and won't do a damn thing to bring one. If someone wants to risk losing a lot of money doing it they are welcome to try. But when the league makes you millions as long as you just have a decent stadium anywhere in the country why take the risk?
Not that he isn't above the hypocrisy, but lets be realistic here. We aren't the constituents the NFL cares about. The only group the NFL cares about significantly are its bankers. The bankers say Tags has been a screaming success. When he came in the league people were aghast at $200 million dollar sale prices on teams. People now don't flinch when a lousy team with a mediocre fan base sells for $550 million like the Falcons did some years ago.
