The last time ND went to L.A. undefeated and lost was 1980. That was 38 years and eight coaches ago.
The last time ND went to L.A. as a clear-cut favorite and lost was 1996.That was 22 years and six coaches ago.
None of that stuff has jack to do with ND and USC this weekend. One team is undefeated, elite and playing for a national title. The other is 5-6, has played like a team that's 5-6, and is playing for a chance at a spot in the Cheez-It Bowl.
There isn't any relevant recent history of ND being upset in L.A., or really of any legit underdog in this series losing regardless of location.
