I agree that the Fox contract will be an issue. But hopefully the clubs get creative esp with the online rights. Most new startups are begging for content. Theres money to be made as live sport are still the most coveted rights out there.
i cant see wages/salary cap being an issue though. The clubs will jsut allow more competition from sponsors, they'll allow owners to spend more of their own cash anyway, which most seem more than happy to do (Tony Sage has been leading this for 10 years).
Once they start earning money from transfers between clubs and utilising that asset as well, then smart teams will go closer to running their clubs like the rest of the world.
