Last week we broached the subject of what a second Super Bowl win might mean for Peyton Manning in terms of his standing among the all-time great NFL quarterbacks. How about off-the-field though? Manning already is the NFL's most marketable player by a mile. His endorsements with the likes of MasterCard, Sprint, Gatorade (owned by PepsiCo) and Oreo (owned by Kraft) are worth in the neighborhood of $10 million annually, more than twice as much as any other NFL player. The closest NFL guys to Manning in terms of off-the-field income are two fellow QBs he knows well: his brother Eli and the Patriots' Tom Brady. They both make an estimated $4 million annually.

To see what another Super Bowl win might mean for Manning, we checked in with Ryan Steelberg, chief executive of Brand Affinity Technologies (BAT), which pairs advertisers with endorsement talent. BAT has footage of its athletes ready to be used in commercial campaigns so deals can be struck and put in place quickly as online flower web site ProFlowers did with QB Drew Brees after the Saints won the NFC Championship game.

"This Super Bowl provides a new and significant opportunity for Peyton Manning to reach an international audience," says Steelberg. Typically the Super Bowl audience is very U.S. centric. The game is broadcast in more than 200 countries, but estimates put the typical viewing audience outside of North America at only 10 million (the average U.S. audience for last year's game was a record 99 million people). Steelberg thinks this year is different and he points to the history of New Orleans and several other compelling story lines like Pierre Garcon's relief work for the people of Haiti that make this Super Bowl a truly international event. He adds: "This Super Bowl may mark the moment that Peyton Manning becomes an international star, which will ultimately increase his endorsement earnings potential."
