The article describes the evolution of U.S.C.'s offense since 2001 and the marginalization of Norm Chow. Pete Caroll was unhappy with the offense after the 6–6 campaign in 2001 so he overhauled the run blocking schemes. In the process, he got further and further away from Chow's offense. U.S.C. hasn't been as dominant since Chow left. This helps explain why Chow left.
