The Cavaliers take on long-time rivals the Detroit Pistons tonight at 7:30 at Rocket Mortgage FieldHouse. The Pistons haven't had a potent team since the days of Ben Wallace, Richard Hamilton, Chauncey Billups, Rasheed Wallace and Tayshaun Prince, and they don't promise to be very good this year either. The Boston Celtics, another long-time rival, come to the arena tomorrow night for a game that begins at 8. Check the Rocket Mortgage FieldHouse website for ticket prices.
