The Atlanta Hawks have signed Keaton Wallace to a one-year deal, according to Shams Charania of ESPN. Previously on a two-way contract, Wallace impressed during the preseason with 20 assists against just five turnovers. Though his scoring was modest, his ability to facilitate makes him a potential asset off the bench. With Wallace’s two-way slot now filled by Caleb Houstan, the depth chart will be one to watch, especially as Nickeil Alexander-Walker joins the backcourt mix.
