Why would they be disappointed ?I think you guys that are tying yourselves to the Sunday Ticket are going to be sorely disappointed when the agreement runs out and the NFL launches it's own streaming service, team by team.
IF that would happen, they'd be able to save money on thier Sunday Ticket, maybe ...
Then again, all those other people you mentioned that might be able to get the ST, may find out that you DON'T save any money as those companies already see what customers are willing to pay to D*, so they may come out and still charge $300+ for the ST (thier versions)
As for the NFL selling it by the team .... thats an interesting idea, depending on how much they as per team.
If they ask $100 or more for the TEAM version (which I think they would) I doubt i'd go that route, I suppose $100 would be tops for me, I might consider it (but only if I could get it anywhere I want, so its not limited to 1 location, none of the streaming services are tied to one location.).
I would probably have to see what the Full package price is, you got to consider watching 1 game one that Sunday vs ALL of them.
