9:51am: After letting go of James Nunnally at the end of his second 10-day contract, the Hawks are now adding small forward Cartier Martin on a short-term deal, according Shams Charania of RealGM. Martin recently played out consecutive 10-day contracts with the Bulls, who declined to extend him for the rest of the year.
Martin was released by the Hawks earlier this season, then performed well in his limited time with the Bulls, shooting over 60% from both the three and the floor overall. In his six seasons, the Andrew Vye client has career averages of 5.4 points and 2.0 rebounds on 14.4 minutes per game.
