9:54pm: The Grizzlies have officially traded Mack to the Hawks in exchange for Dorsey, the team confirmed on Thursday (Twitter link).
Mack, 28, has been Memphis’ backup point guard for the 2018/19 season, averaging 7.9 PPG and 3.4 APG in 53 games (22.7 MPG). He has also had one of his best three-point shooting seasons, knocking down 35.9% of his attempts from outside.
However, Mack is expected to be waived by Atlanta, per Chris Vivlamore of The Atlanta Journal Constitution (Twitter link). If those are the Hawks’ intentions for Mack, it’s not clear what their motivations are for making the deal.
As for the Grizzlies’ side, sending out Mack for Dorsey allows the retooling squad to replace a veteran with a young prospect who had taken a step backward in Atlanta this season. A second-round pick in the 2017 draft, Dorsey posted 7.2 PPG and a .362 3PT% in his first year, but those numbers have dipped 3.3 PPG and a .256 3PT% in year two, as he has seen his role cut back.
