Coming out of Wichita State in 2018, Shamet was selected 26th overall by the Sixers during the NBA Draft. The young guard averaged 20 minutes on the floor in his first 54 games in the NBA.
During that time, Shamet averaged 8.3 points per game while shooting 40-percent from beyond the arc. The following year, Shamet played the entire season on the Clippers. During the 2020 NBA Draft last fall, Shamet was sent packing to the Brooklyn Nets, where he would play the entire 2020-2021 season.
