Cam Newton, who's expected to be one of the first quarterbacks taken in April's NFL draft, signed what CNBC.com reports is the most lucrative endorsement pact ever awarded an incoming NFL player. Under Armour, the athletic apparel and footwear company, gave the Heisman Trophy winner a contract that seeks to capitalize on the momentum of his leading Auburn to a national championship as well as his potential as a professional endorser.
