in reality away fans dont number anything like that many and most home fans pay nothing like £25 a game, not to mention concessions. Many clubs ( eg wigan in your example) make zero from sales at the stadium. Your maths is flawed.

wakey and cas still havent fulfilled the franchise requirements from last time around. I'm not sure how Salfords rental works but Hudds and Wigan pay a rental based on the numbers attending. the smaller the attendance the smaller the rent. so if attendances drop so does the outlay.

I think that requirement died with licensing and is clearly no longer a pre-requisite of Superleague membership.

I've been in Belle Vue when it sold out for the Cas play off game, and it was a fantastic experience. Equally I've been at Huddersfield in their modern stadium before some very low SL crowds that wasn't that great.

Grounds need to be safe and that includes not over filling them, and that's about it for me unless I wan't to goad any Wakey or Cas fans on here which I don't. I'm not suggesting you do either BTW, but it happens all too often......
