A meaningful TV deal will never get done as long as MLB owns the team. All the questions as to what to do, or even complaining, wont change that fact. Fas got 81 games last season, to help Peter Angelos and the MASN deal look better than it was.
MLB has shown everyone on the planet, that it cannot be trusted, that greed is its number one motivator. They (the Nats) get the same amount for TV rights no matter how few games are on TV. If MLB was a tree, it would have been uprooted or snapped in two long ago, because it's unwilling to bend to accommodate anyone, except one of its own, and as we have all seen, certainly not a city or its fans. If anyone ran their business like MLB does their's, they wouldn't last very long.
If you want a TV deal that has more umph to it, you can either try and convince the Lerner or Malek groups to increase their offer to $500 million to take over the team right now, or more practically, approach Comcast, Cox or whoever, en mass, and I do mean en mass, not a few hundred people, because the people (subscribers) have the power, after all, companies here the voices loudest and most clearly when there's fear that money might be lost.
MLB is in no hurry to sell the team, why should they be. They saw last season, they have a gold mine on their hands, and the selling price of the team wont be going down anytime soon. From their perspective, there's no rush. They can wait until everything is as they want it, not the DC council, not the players, coaches or management, and not DC fans.
The one thing that does nothing to help improve things, is sitting around and grumbling about what a lousy TV deal they have. Gather all the Nats fans who have cable, and show up "en mass" with demands that they carry not just the same 81 games they had last season, but the 150+ that MASN is producing...
There are thousands of cable subscribers who are also Nats fans. Use that to make your voices heard, use that to give your voices power.
