A 6’8″ forward out of Iowa, Cook played for the Cavaliers and Nuggets as a rookie in 2019/20, then spent time with the Nets and Pistons during the 2020/21 campaign. After signing a 10-day contract with Brooklyn, he inked a pair of 10-day pacts with Detroit and then agreed to a multiyear deal in April. The team waived him at the end of July.
In 32 total games in 2020/21 for the Nets and Pistons, Cook averaged 4.9 PPG and 3.0 RPG in 32 games (13.7 MPG). He made 67.0% of his field goal attempts, but just 48.6% of his free throws.
Chicago has 13 players on guaranteed contracts, plus one on a two-way deal, so there are at least a couple spots up for grabs on the 17-man regular season squad. Cook figures to compete with the team’s other recent signings for one of those spots.
