"Since Kurt Warner hung up his cleats, the Cardinals are 6-15. The Cardinals invested a bundle in quarterback Kevin Kolb, who has just 12 starts in five pro seasons, for a bland 4-8 record with more interceptions (20) than touchdown passes (16). On his career, Kolb also has been sacked once every 15 times he drops back, versus, say, Drew Brees being sacked once every 27 times. Young quarterbacks often struggle -- Brees did. But in his five seasons, Kolb has played only one really good game. Sunday, he was lifted for Richard Bartel, undrafted out of Tarleton State, who's been waived by four NFL teams and appeared briefly with the Sacramento Mountain Lions."
