Riddick had runs of 55 and 27, the two longest rushes of his career, to pace Notre Dame (7-0), which is off to its best start in a decade and has a big game ahead against No. 10 Oklahoma next week. The Cougars (4-4) fell to 0-3 on the road as they surrendered a season-high 270 yards rushing by an opponent.

Backup quarterback Tommy Rees, starting in place of injured Everett Golson, completed 6 of 7 passes in the first quarter for 86 yards and a touchdown, completing four of those to Tyler Eifert. But Rees went cold later and the Irish attempted only three passes in the second half.
