The market determines the value of tickets, concessions, collectibles, etc. If the economy continues to stay in a foul mood, ALL team owners will need to adjust accordingly.
Speaking for myself only, I don't attend games for a couple of reasons. First, the prices turn me off. Years ago, you could take the entire family to a game for a reasonable price and it was an enjoyable experience. Today, you need to budget for it. Eh, forget that stuff. Sure, I will go if someone gives me a free ticket or for a few pesos, but not much more.
Second, the fan experience is not what it used to be. Fans now attend games and in many situations, they fear for their safety - or lives. It's not worth it.
Attend a preseason game? Maybe. Attend a regular season/paloff game? Under certain circumstances only. Attend an away game? Uh, no.
