I don't think they will, but it wouldn't suprise me if they do. Renewals of Curry, Iguodala and Durant are coming up soon. Maybe they want to add big men and other bench players. I don't know if they can afford Curry, Durant, Thompson and Iguodala whilst adding other players.
By adding a scorer like Durant, I think his role as shooter/scorer is a bit dimished anyway. He's a bit expensive to be a 3-and-D guy.
