The Hawks are interested in bringing back Joe Johnson. And a reunion is a real possibility. The Hawks are one of several teams with serious interest in signing the seven-time All-Star and Johnson has interest in the returning to Atlanta, according to several people familiar with the situation. The Nets have begun negotiations to buyout Johnson’s contract, according to a report by ESPN’s Mark Stein. Johnson would have 48 hours to clear waivers once a buyout is reached. He would then become a free agent.
