USC will present at least one different component when the Trojans play Stanford for the second time this season.
Ronald Jones II was a jittery freshman in only his third game when the Cardinal defeated USC in September.
Jones has since become game-tested — and the Trojans' leading rusher — going into Saturday's Pac-12 Conference championship game at Levi's Stadium in Santa Clara, Calif.
"I've definitely grown as a player, with the help of my coaches and teammates, to not play like a freshman," said Jones, who has rushed for 890 yards and seven touchdowns.
