After being selected with the No. 35 pick in the 2018 NBA draft out of Tulane by the Magic, Frazier appeared sparingly for Orlando, logging time in just 10 games with the Magic during his rookie season in 2018/19. The 6’5″ 25-year-old played in 19 contests for Orlando during the 2019/20 season.
Frazier had a better showing with Orlando’s G League affiliate, the Lakeland Magic. He averaged 12.2 PPG and 4.7 RPG in 18 games during the 2018/19 season and 18.1 PPG and 6.6 RPG across 23 games in 2019/20.
After failing to develop in Orlando, Frazier next appeared in 12 games for the Oklahoma City Blue during the Orlando “bubble” NBAGL season in 2021, averaging 6.8 PPG and 3.4 RPG. His new deal with the Thunder suggests the plan is for him to return to the Blue in 2021/22.
