GLENDALE, Ariz. -- It's tough to take the Cardinals seriously beyond the NFC West when they fail to show up at home with a chance to become the NFC's third seed heading into the final two games.
This was an across-the-board meltdown for Arizona.
Kurt Warner was careless with the football early and defenseless against the Vikings' pass rush most of the day.
As a result, Arizona has gone from a likely 10-victory team to one that might need to beat Seattle in the regular-season finale for a shot at topping its 8-8 record from 2007.
Perhaps this outcome will serve as a wake-up call heading into a Week 16 game at New England. The Cardinals had better hope so.
