Pac-12 Networks' Jill Savage talks with Christian McCaffrey, who's 461 all-purpose yards, a Stanford single-season record, propelled the Cardinal to a dominant 41-22 Pac-12 Football Championship win over the USC Trojans on Saturday night at Levi's Stadium in Santa Clara. McCaffrey surpassed Barry Sanders' single season record of 3,250 all-purpose yards well before the game's end.
