What do Herschel Walker, Robert Griffin III, Eddie George, Ricky Williams, and Desmond Howard all have in common? They've all had the chance to hoist a Heisman trophy. Also, they all drive brand new Nissans (at least for these commercials!). The new campaign is set in "The Heisman House," and stars 12 of the trophy winners, along with Rudy actor Sean Astin. For Nissan, the spots are really nothing more than product placement, but almost all of them gave us a chuckle. Who wouldn't want to laugh at Matt Leinart, see RGIII trimming bushes, or watch Ricky use telepathic hook 'em powers to move a longhorn?
