Brett Favre’s rugged handsomeness won him Wrangler ads and Peter King’s heart, but it also might have made him some sweet moolah as well.

A new study, examining 121 quarterbacks from 1995 to 2006, shows that attractiveness, measured by facial symmetry, significantly affects a quarterback’s salary.

Attractive quarterbacks, such as Kerry Collins or Charlie Frye, earned $300,000 more then they merited, while asymmetrical uggos, such as Neil O’Donnell and Jeff George made $300,000 less than they should have.

Hidden under that scraggily salt and pepper beard, Favre had the most symmetrical face of the quarterbacks examined. Suck on that, Brady!

Expect Jason Whitlock to rebut, with his unique expertise, that Jeff George really is attractive.

Third-string quarterbacks, according to the study, received the largest benefit, suggesting that the old cliche about how good they look holding a clipboard may have some merit.
