On Thursday, the Wizards announced that they traded guard Sheldon Mac to the Hawks in exchange for a protected second round draft pick in 2019. Mac suffered a season ending injury in an exhibition game, but was still taking up a roster space and his salary counted against the cap.
This trade frees up a roster space for the Wizards. They now only have 13 players, leaving two spots open to potentially be filled with free agents. Mac will stay in Washington to continue his rehab process for the time being, and will presumably join the Hawks roster at the beginning of the 2018-2019 season.
With the Cavaliers totally re-shaping their roster, and stars such as Blake Griffin being traded, small moves such as this went largely unnoticed. This move will not affect the Wizards this season, but helps them in the foreseeable future by adding young talent through a draft pick and roster space.
