Talk about sticking it to you. The Arizona Cardinals are making an effort to thwart Dallas fans from turning the Oct. 12 game at University of Phoenix Stadium into a Cowboy home game. If you want to buy a single-game ticket to the Cowboy game, the Cardinals are you by  making you purchase a ticket to the exhibition game against the New Orleans Saints on Aug. 7. The concept probably won’t deter anyone who can actually afford to go to Arizona to see a Cowboys game, right?
