Let's raise the seating ceiling to 80k or even 100! As a club owner that also owns the stadium it plays in, I'd like to grow the stadium to attract the summer rock tour season. Wembley fit 85000 in for U2 in 2009. I'm sure we could top that up here in Scotland for a Big Country / Simple Minds reunion tour. The extra cash could then be used to subsidize football operations.
Along these lines, future updates could include a daily or annual expense for stadium security and amenities. Skimp on these too much, and hooligans descend, driving attendance figures sharply lower. Sidelines like these could keep owners interested in the game more regularly, especially as the game matures and teams must learn to grow talent from the bottom-up over a real-world period time of many months if not years.
