More than 370 sets of brothers have played professional football, according to the Pro Football Hall of Fame.
Brothers Brad and Daniel Sorensen would like to join the uncommon fraternity this season.
Brad Sorensen, 27, is now with the San Diego Chargers as a third-string quarterback. Daniel Sorensen, younger by two years, is third on the depth chart at free safety for the Kansas City Chiefs.
Born into an athletic family in Colton, California, the Sorensen boys grew up competing against each other. Now they share the common goal of each making their respective teams, which happen to be AFC West division rivals.
