It has been suggested many times by fans of Premier League teams (& the media) that they should drastically reduce prices,as they can easily afford it now with the new TV deal.
If all Premier League tickets were reduced to say £10, what would happen to Championship clubs. They would either have to respond by reducing prices to less than £10, or be in the unsustainable position of charging more than double the amount of a PL ticket. Either way, most non PL teams would be out of business within 5 years.
I really don't think so. People don't generally just switch teams willy nilly do they? And non PL teams are fairly likely to start going out of business anyway IMHO. Football is in a terrible state.
