FILE – In this Jan. 5, 2014, file photo, Green Bay Packers quarterback Aaron Rodgers looks to pass against the San Francisco 49ers during an NFL wild-card playoff football game in Green Bay, Wis. Signing with an agent usually is the first career move a college player makes in turning pro. Some agents boast their successful clientele at certain positions, or alumnus from certain schools. ?A lot like a restaurant, it?s word of mouth, but frankly (that) isn?t the worst way to build a business,? said David Dunn, who represents Rodgers among the stockpile of players represented by his firm, Athletes First.
