Seeding
Six of the twelve Western Athletic Conference men's soccer programs qualified for the 2021 Tournament. California Baptist and Dixie State were not eligible for the tournament as they transition to Division I. California Baptist would have been the 5th seed if they were eligible. Teams were seeded based on their regular season records. Tiebreakers were used to determine the seedings of teams who finished with identical conference records. A tiebreaker was required to determine the 2nd and 3rd seed as Seattle and Air Force finished with identical 8–3–0 records. Seattle earned the second seed by virtue of a 2–1 victory over Seattle on October 16.[4]
