And what if they had "thrown away" Barnes after he had struggled his first few years or decided to bring in a veteran and give Green 5 mins or so off the bench. Sign Pleiss, continue to explore trades for Burke (that would be icing on top), but Bake The Damn Cake!
They could probably replace Barnes pretty easily.
Never suggested giving away Hood (I guess Hood is Barnes in this analogy) or giving Green 5 minutes per game (I guess that is Lyles?). It's just adding a high level wing (Igoudala).
