I would hope that as a minimum, all the clubs in the top flight are playing in modern facilities with everyone spending to the cap. Everyone spending to the cap would see a natural increase in the quality of the product and therefore an increase in crowds.
Hopefully Leeds, Wigan and Hull pushing 16-18k average.
Saints, Wire, Bradford, Catalans pushing 13-16k.
Hudds, Hull KR, Castleford getting 10k+
Not really sure which other teams would be in super league but I would hope we could increase the pool of players enough to have 16 teams by then. But if not then just those 10 teams would do for me. Maybe Barrow and their football team can get together with the council and build a new ground so we can have a team from cumbria. Maybe Widnes will be a great success and stay in the league for years to come, we might even see other great clubs in times gone by coming back to the top. Who knows? Maybe another team in France!
One thing is for sure, by 2025 we need to be getting more people through the gates and watching the sport to increase income and increase sponsorship.
