There absolutely is. The logical decision for both the customers and the resellers is to make the Premier League package cost around 100/120£ per year. And trust me, there would be an increase in revenue (not that is needed for the Premier League) because so many people would be so interested in only watching the Premier League. The only problem an all-PL package would cause is the decrease in revenue for every other League in the World, and that would be especially noticeable for the Championship.Yeah, that's exactly what I'm saying though. Sky would be cheaper without the PL. But wherever the PL goes will be more expensive, significantly so if it's a PL-only package that isn't spreading the cost among additional subscribers.
There's no way an all-PL package would be 9 quid a month. It would probably be closer to 100.
That would price out a ton of fans, even worse than currently. That's why they don't want to do it.
