Just on this last point, if there are games at Subi that didn't sell out, what makes the Eagles think they need an additional 15,000 member tickets? Surely In the Wings members would be filling up any unused seats. This is part of the reason I don't think the Eagles' numbers stack up. I think there are plenty of In the Wings members that would prefer to be a casual fan but signed up because seats were limited otherwise.
A three game membership may go some way to addressing this and it is an option I am expecting,
You are simply reflecting the undersupply at Subi for the excess demand, pure & simple, no ifs, I thinks or other theories, e.g I'd prefer to be a casual fan aka I want the same product for less money & want someone else to pay - bit blunt Jack but that's how you come across.
I do agree there should be a fair size number of 3 game memberships with members holding this package receiving preferential offers to step up to full season reserved seating members.
