My alma mater's college basketball team is playing a game tomorrow that is only being shown in my area (ironically in Philly, the area where the school is based) on the YES network. To get the YES network would require ugrading 2 levels for FiOS TV at a monthly cost of $35, which is a lot of money. My question is if I upgrade, I assume I can downgrade back to the original package, but how long would I have to keep the new package before I could downgrade?
