I’ve only ever been involved during the summer but there are 6 games a week in the Pennine League this season and I’d say on average so far about half of them get called off.
I don’t think switching back to winter would change much, I know you get the drop off during school summer holidays (junior rugby takes a break in august anyway) but if people preferred to play in winter then surely there’d be more teams playing in Pennine League and BARLA winter cup comps.
Someone I work with was telling me about how many football leagues there were in Castleford back in the 80s and now it’s all part of the Wakefield League so it’s not just a rugby league issue. It’s a societal one, there’s no pub or work teams anymore, people have more options of things to do, young people don’t play sport as much, the list could go on.
