As an Arizona resident and Cardinal hater my favorite team is whoever is playing the Cardinals.
The Bidwells are among the worst owners in the league and don't deserve a ring. They forced the Cardinals to play in a college stadium from 1988 - 2005. From 1988-2007 they compiled a record of 123-229 with 0 seasons above .500, 3 seasons at .500, and 1 playoff appearance and 1 playoff win, both in 1998.
I'm certainly not a Homer and while my heart says Steelers my head says Cardinals. The Steelers have a great defense, but I don't think they can contain Larry Fitzgerald, Anquan Boldin, and Steve Breaston.
