In general I think that's a good idea for rebuilding teams that won't be using their cap space on big FAs anytime soon. In this particular case I'm not sure, as we have so many picks already. How many rookies do we really want to be developing over the next few years? It really only makes sense if you can turn quantity into quality. Trade 5 future picks for a rare talent like Embiid, or 3 for a potential star like Aaron Gordon.
