The Pac-12 tournament moved to Las Vegas a decade ago. During its stay on The Strip, the event has typically unfolded as expected with just two teams seeded lower than No. 3 claiming the trophy: Oregon in 2019, as the No. 6 seed, and Oregon State in 2021, as the No. 5 seed.
Based on a regular season that produced a dominant champion (UCLA) and a clear second tier (Arizona and USC), the likelihood of a surprise winner seems low.
