STANFORD, Calif. — The biggest hit to Andrew Luck's Heisman Trophy campaign might come from his own teammates.

Stanford's running game has quietly been one of the nation's best the past few years despite often being overshadowed by Luck's passing. But after setting a school record with 446 yards rushing in a 65-21 throttling of former No. 22 Washington, the Cardinal running backs now might have a hard time hiding.

Same might go for the entire program.

Stanford climbed to No. 4 in the AP poll on Sunday after losses by Oklahoma and Wisconsin. With a stable of running backs leading the way and an offensive line as powerful as any, Luck might have all the help he needs heading into a big matchup at No. 20 Southern California.
