National title implications hover over South Bend

The USC-Notre Dame football series began in the 1920s and was a great rivalry.

When Knute Rockne died in March of 1931, the series lost a little of its luster, although the game that fall -- in which USC trailed 14-0 but came back to win 16-14 -- remains one of the greatest victories in the history of Trojan football.

Lore says the victory parade after the game drew more than 100,000 people to downtown Los Angeles.
