The San Diego State Aztecs enter a new era in the Pac-12 conference
In short: After nearly three decades in the Mountain West, the San Diego State Aztecs are embarking on a transformative journey. As they join the Pac-12 for the 2026 season, the program faces significant shifts in leadership and preparation, marking a pivotal chapter for the team under head coach Sean Lewis.
The 2026 season represents a historic transition for San Diego State University. Following a 27-year tenure in the Mountain West conference, the Aztecs have officially moved to the Pac-12. This shift in conference affiliation brings new competitive challenges and visibility to the program, which continues to play its home games at the modern Snapdragon Stadium in San Diego.
Stability in coaching remains a primary focus for head coach Sean Lewis, who enters his third year at the helm. The defensive staff underwent a notable change late in 2025. Following the departure of defensive coordinator Rob Aurich to Nebraska on December 7, 2025, the team acted quickly. Demetrius Sumler, previously the cornerbacks coach, stepped in as interim coordinator for the New Mexico Bowl before being promoted to the permanent position on December 20, 2025.
Preparation for the inaugural Pac-12 campaign has been rigorous. The team initiated their offseason program on January 23 with a nine-week block of winter workouts. This foundational period transitioned into spring practice, which commenced on March 23. The program is set to conclude this phase of development with a spring game held on the San Diego State University practice fields on May 2, signaling the final push before the regular season begins.
This transition is significant not just for the players, but for the university's athletic identity. By moving to a conference with a storied history like the Pac-12, the Aztecs are positioning themselves within a new tier of collegiate competition. Whether this move will translate into immediate success remains to be seen, but the structural adjustments made during the winter and spring suggest a program focused on maintaining continuity despite the high-profile change in league membership.
