He was replaced as the USC head coach by Larry Smith after the 1986 season after going 1–3 in the UCLA–USC rivalry and 0–4 vs. Notre Dame in the Notre Dame–USC rivalry. In 1994, he returned to San Diego State, this time as the head coach. He coached there for eight years. Tollner was known for scheduling a tough non-conference schedule including schools like Washington, Wisconsin, USC, Arizona, Arizona State and Oklahoma. His Aztec teams posted eight-win seasons in 1995 and 1996, the first time it reached that level in consecutive years since 1977. In 1998, his Aztecs posted a 7–1 conference record, grabbed a share of the conference championship, and earned a trip to the Las Vegas Bowl.
