It’s the 1981 Crosstown Rivalry at the Coliseum.
Below, here’s an excellent photo of George Achica’s most famous USC moment, as he blocked Norm Johnson’s 46-yard field-goal attempt to preserve the Trojans’ 22-21 victory.
Achica missed the previous two series with a slightly separated shoulder but Marv Goux put him back in for the field goal. Charles Ussery and Dennis Edwards went low to open a hole for Achica.
The photo was taken by Sports Illustrated’s Peter Read Miller, a former USC student who took photos for the school yearbook.
