I Really Don't see DirecTV not getting a deal done for YES. I'm not a big Baseball fan, but DirecTV prides itself on being the service of choice for Sport Fans in general. Not having THE default Biggest franchise in one sport would be a DirecTV killer, and or a huge Black Eye for DirecTV.
Do I believe Dish will drop SNY? Absolutely, Dish has already proved they don't care about NY sports fans be refusing to sign a deal with YES, then the removal of MSG in October last year. Removing SNY would complete the trifecta and eliminate all NY sports teams completely. I became a DirecTV sub specifically for access to MSG (Buffalo Sabres Fan here).
