Beer sales are such a small percentage of team revenue, all it will take is a few more high profile - a fan died - kind of events and we could be headed that way. Tickets are too expensive to have to endure drunken haymaker fights. Now, will there be a lot of drinking before the game outside - hell yeah.
The money is not in the stadium anymore. The money is on your tv set. The ticket sales, beer sales, parking, etc is just gravy.
