Rosenberg's post stated that Amundsen will be seeking "different opportunities," with the possibility of hopping onto a college coaching staff.

As reported detailed by Seliga's report, Amundsen compiled a record of 159-62 during his eight years with the Tigers. The team became a power on the national stage and won four Arizona state championships. Millennium also appeared in the prestigious City of Palms Classic in Florida twice during Amundsen's tenure, making it in the national bracket during both appearances.

Amundsen also coached at St. Mary's High School in Phoenix, from 2012 to 2017 and Estrella Foothills High School in Goodyear, Arizona, from 2006 to 2012, where he won three state championships.

During his tenure as a high school head coach, Amundsen had two players reach the National Basketball Association (NBA), featuring current Denver Nuggets forward DaRon Holmes and current Atlanta Hawks assistant coach Corey Hawkins.

Millennium finished the 2024-2025 season with a 20-8 record and reached the Arizona Independent Association (AIA) Open Division Semifinals where they lost to runner-up Sunnyslope back in March.

The Tigers were led last season by 6-foot-6 rising five-star senior combo guard Cameron Holmes, who holds offers from Arizona, Arizona State, Dayton, Georgetown, Oregon, and several others. Another key contributor to the team was 5-foot-9 senior guard JT Amundsen, who is the son of Ty where he is the school's all-time three-point shooter.
