You know the game was great and all, but I think there were shades of what happened in SB XL. Nothing as blatant, but did you notice that EVERY time the Cards o-line held, it got called, but I think the Stealers got called one time and with that much maligned o-line, I am sure they held more than that. Then at the end when they called Warner's "fumble" and subsequent Pittsburgh recovery, they did not even review it and let the Stealers line up and kneel.
I don't believe the game is fixed, but I do believe the refs are biased, and it would not at all surprise me if they were instructed to be so in both games. It really disgusts me, but they are playing to the market.
Pittsburgh is the most popular NFL team, therefore it helps the NFL for them to prevail. Had the game been Arizona vs Baltimore, there would have been no bias as both teams are small market and largely unpopular, but I think then the Cowboys, Steelers, Packers, and maybe a few other teams are in the big one the refs are encouraged to give them preferential treatment and try to make it look legit.
Bottom line is that the Cardinals could still have won, and failed to do what it takes, but the Stealers have had help twice now in my opinion.
