I had the same problem. The games are blacked out if they are televised on any other platform. The team I follow (Cowboys) is an out of area team but they were blocked all but for 3 games. Those three games weren't even good games.
It wasn't worth it. I'd like to see a model where the games are pay per view. Let me pay by the game when I want to watch.
I'd even buy a season of a single team's games as a block, if there were never black-outs. I grew up in Boston, so I usually want to watch the Patriots, but NFLST would sometimes black-out their games even though they were almost never available over boadcast in my market. No idea why, but I still had to pay for those weeks!
