Atlanta: Assuming the Hawk's main issue continues to be defense, there is no reason for them to deny this trade. They get two elite defensive cornerstones in OG and Claxton. They don't give up any particularly good players, but it is hard to see the picks go. With this being said however, Atlanta's picks won't likely be terrible, but they aren't likely to fall in the lottery either. I think the need to break the cycle of mediocrity will drive this trade for the Hawks.
Brooklyn: They aren't looking to compete this year, and the addition of a quality role player, young talent, and picks helps their future.
Toronto: They aren't looking to compete this year, and the addition of a quality role player, young talent, and picks helps their future.
