GLENDALE, Ariz. -- The Cardinals are finally for real.
They needed overtime to prove it, but their 4-2 record and consecutive victories over Buffalo and Dallas left little doubt. This was the victory Cardinals coach Ken Whisenhunt needed to demonstrate how far his team has progressed.
Previous road losses to the Redskins and Jets raised questions, but the Cardinals answered them with two impressive victories heading into their bye.
Arizona didn't get many breaks in this game. The officiating worked against them repeatedly. They lost cornerback Rod Hood, who had been defending Terrell Owens.
They even lost the coin toss to begin overtime.
But they still found a way to win when Sean Morey blocked a Cowboys punt and Monty Beisel ran it in for the decisive points. The Cardinals will have a hard time losing their division lead after the Seahawks and 49ers lost again.
