Rick Sund, the general manager of the Hawks gave an interview to ajc.com where he is answering questions from journalists and fans alike. Regarding the case of Josh Childress(2.03-SF) that plays currently for Olympiakos he said the following:
MB: Do you talk to Childress?
RS: He’s playing right now in Greece … When their season is over, they’re going to inform us. Evidently he can opt out of his contract. If he opts out, we’d have to tender him a [one-year] qualifying offer. Otherwise he’d be an unrestricted free agent.
MB: So you’ve had no contact with him during the year?
RS: We’ve had scouts go over and watch him. [Assistant GM] Dave Pendergraph has texted him. And I’ve talked to his agents – they represent other players.
MB: And what was your read on Childress?
RS: They played it pretty close to the vest.
