A few minutes after his Stanford teammates left the field, Andrew Luck sprinted toward the Coliseum tunnel with both arms thrust triumphantly skyward, his heart still pounding from 56 points, three overtimes and a season's worth of drama packed into one crazy night. After nearly a full calendar year of blowout victories, Luck and the Cardinal (No. 6 BCS, No. 4 AP) might have forgotten what a thriller feels like. Luck loved it all, right down to the final Southern California fumble that ended Stanford's 56-48 triple-overtime victory over the 20th-ranked Trojans on Saturday night.
