I think Philly cares very much about developing their players. Their entire system is built around developing players. But I'd say you are correct in that they don't care about winning right now. If all goes as planned, embiid will get healthy and they will have an interesting young core next year of wroten, stauskas, saric, Simmons, Noel, okafor, and possibly three other 1sts (one as high as 4) and whatever other young assets have stood out like grant. At that point they can maybe fill out the roster with vets using the 70ish million in cap space they have available.
You can think they suck right now (they do) but philly is a GM's dream. You don't get any more flexible than that. They have unlimited assets to do basically anything. Consider how much we'd have to give up just to get Okafor from them. They have unlimited options.
Love what Minny is doing as well but Minny doesn't have two of their potentially best assets off the table this year. They can try to win this year and the only loss will be their draft pick if it ends up 13+.
