Unlike Buffalo, most season ticket holders are corporations and speculators. I know many season ticket holders here in Washington that have tickets, but have not gone to a game. It is an investment. When you sell your tickets for a profit (stubhub, ebaty, craiglist, etc.) you take the highest price. Not the highest price from a home team fan.
I have long contended the easiest way to quiet rival fans....WIN! If you win the game, then rival fans stay quiet. Otherwise, what you see is just business at work.
