The Pac-12 Defensive Player of the Year is an annual college basketball award presented to the top defensive player in men's basketball in the Pac-12 Conference. The winner is selected by conference coaches, who are not allowed to vote for players on their own team.[1] The award began in 1984,[2] when the conference consisted of 10 teams and was known as the Pacific-10.[3] It stopped being issued starting in 1988 but was restarted in 2008.[4][5] The conference added two teams and became the Pac-12 in 2011.[3]
Jorge Gutiérrez of California (2012) and Evan Mobley of USC (2021) are the only players to also win the Pac-12 Player of the Year in the same season.[2][6]Gary Payton won both awards in separate seasons with Oregon State, capturing the defensive honor as a freshman in 1987 and the conference player of the year as a senior in 1990.[7][8] He credited Beavers coach Ralph Miller with molding him into a standout defender. Payton played 17 seasons in the National Basketball Association (NBA), and became the only point guard to be named the NBA Defensive Player of the Year.[7] His son, Gary Payton II, later played with Oregon State as well, and was voted the Pac-12 Defensive Player of the Year in 2015 and 2016.[9] He and Matisse Thybulle (2018, 2019) are the only repeat winners of the award.[10]
