Cooley had originally committed to the University of Minnesota (NCAA) for the 2023-24 season but has decided against that decision as he signed a three-year, entry-level contract Thursday with Arizona. The 19-year-old centre was Arizona's 2022 1st round-pick (3rd overall) and had 22 goals, 38 assists, 42 PIMs and a +38 plus/minus through 39 games with the University of Minnesota in 2022-23.
