San Diego State has promoted EDGE coach Rob Aurich to defensive coordinator.

Head coach Sean Lewis made the hiring official on Friday.

Aurich held the same position at the University of Idaho for two years before coming to The Mesa with Lewis last season. The Vandals’ defenses improved significantly under Aurich’s leadership.

U of I gave up over 30 points per game in the three years before Aurich took over. That number improved to 25.42 ppg in 2022 and 22.08 in 2023. The Vandals were the fourth seed in the FCS playoffs in Aurich’s final year in Moscow and hosted a postseason game for the first time in 30 years.

Aurich began the week as a dark horse to win the job. Sources told EVT that at least four outsiders to the program were considered for the job.

It was thought one of them would be selected, but Aurich won Lewis over with a detailed, game-by-game analysis of the 2024 season. Aurich’s knowledge of the scheme and the players on the team gave him an edge over the other candidates.

Sources also indicated that Aurich received assistance from one of SDSU’s defensive leaders. Team captain Trey White lobbied for Aurich.

Lewis cast a wide net to fill the role. Ultimately, the best person for the position, according to Lewis, was already on staff.

That he does not have to win over the locker room and can build off last season also bodes well for the decision.
