Short answer is that as far as I am aware the new TV deal really doesnt effect the Mets in next few years positively. Everyone is getting equal amounts from TV deal, so if Mets are behind certain franchises and ahead of others, it wont change those factors. They're also locked into a well below market deal with SNY that they borrowed against, so TV won't be helping them much if at all, especially since programming aside from Mets have been wasted on that network.
As for NY Real Estate market, that is far from what I know about but I will say this: the market doesn't matter if the parts going up are not affecting Sterling Enterprises. And there are still mountains of debt they have coming in 2014 and 2015. Even if TV and real estate help, it likely will go into paying off debt well before the personnel payroll. My suggestion to Mets fans is until they spend assume payroll is going to be in the $60-80 range for the foreseeable future once Santana/Bay are off the books after this year.
Obviously there is d'arnaud, who while a prospect there always will be questions till he does it at this level, seems to be as close to a sure thing as mets have had. It is much harder to find infielders than outfielders, and mets are set. If the pitching turns out to be as good as expected, the mets are only 2 position players and a closer away from being a complete team. Plus, with 2 wild cards, there's always hope. Hey, you never know, they may surprise this year. If oakland and baltimore can, why not mets?
