Madison Avenue loves Super Bowl winning quarterbacks, from Tom Brady to Peyton Manning. So the question must be asked: What did the current Green Bay quarterback do wrong?

Aaron Rodgers took home Super Bowl MVP honors and has the Packers off to a perfect 4-0 start this season. He's clean as a whistle and his jersey sells like Wisconsin brats. Yet No. 12 hasn't piggybacked that success into endorsement dollars.

Brand Week reports State Farm Insurance is the only big-name brand to sign up the MVP of Super Bowl XLV. People handling Rodgers career as a pitchman say he's taking the slow road into the endorsement world, not wanting to be overexposed.

Rodgers did pick up an amusing regional spot for a Wisconsin bank. In the TV commercial, the Packers quarterback hangs with Edith, an elderly lady at a beauty salon talking football as they read magazines and sit under hair dryers.

Despite the quality of the spot, Associated Bank is running the commercial only in Wisconsin, not Illinois and Minnesota where they also have branches. (Now why wouldn't this ad work with Bears and Vikings fans?)

Rodgers leads the NFL with a 124.6 passer rating. He's second in touchdown passes (12) to Tom Brady and tops in completion percentage (73.1). But while Brett Favre is still selling Wranglers, Rodgers is selling safe money.
