It will take 5 years to be in contention, so what's the point of trading top assets for 50pt players, right now? You can sign the 28-30 year olds for more money, for free, (cap doesn't matter) and fill that hole until you need to address it when the team gets better, and still draft the top players in the draft the next 2 years. You still have those assets in 3+ years, you can trade them for that type of talent then, when they are closer to being legit.
I think the Hawks focus on guys who aren't getting long term deals, and give them slightly more to play on a losing team, or take swings on lower line talent in free agency. Maybe trade a 2nd for a younger player in need of a scenery change, but don't see them trading top assets for 24/25 year old 50 pt players.
