Klay Kubiak is in his second season as the 49ers assistant quarterbacks coach. He served as a defensive quality control coach with the team in 2021. Kubiak joined the 49ers after spending the previous three years (2018-20) as the head coach at Strake Jesuit College Preparatory (Houston, TX). He also served as the school's offensive coordinator from 2013-15 and for the 2017 season.
San Francisco saw three starting quarterbacks during the 2022 season, with rookie QB Brock Purdy becoming the team's starter in Week 13. The 49ers offense remained explosive, as the team ranked fifth in the NFL in yards per game (365.6) and averaged 5.9 yards per play, the fourth-highest mark in the league. Purdy went 7-1 as a starter, including the playoffs, and became the first quarterback in franchise history to win their first five starts and the third rookie quarterback in NFL history to win at least their first five starts.
Kubiak and the 49ers defense ranked third in the NFL in 2021, allowing 310.0 total yards per game. San Francisco also was sixth in the NFL, surrendering 206.5 passing yards per game. The Niners forced 22 fumbles on defense in 2021, the most in the NFL and the most in a single season by the 49ers since 1994.
During his three seasons as head coach at Strake Jesuit, Kubiak led the Crusaders to a 24-11 record and a playoff appearance in each season. Kubiak is the only coach in the school's history to win double-digit games as part of the University Interscholastic League (UIL), which Jesuit joined in 2003.
Kubiak attended Colorado State University where he was a quarterback for the Rams from 2007-10. He majored in English at the school and would later earn a master's degree in the subject from Texas Christian University in 2013. Kubiak used his educational background to teach English at Strake Jesuit College Preparatory.
A native of Houston, TX, Kubiak is the son of longtime NFL coach, and former 49ers quarterbacks coach, Gary Kubiak. His brother, Klint, is the offensive coordinator of the Minnesota Vikings. Kubiak is married to his wife, Marissa.
