Fultz is perfect for the Sixers and is following the blueprint of sitting out his rookie season due to injury. In all seriousness, I think Embiid, Simmons, Fultz is a very good core for Philly but I am (and always was) happy with the trade.
It is funny about the two big trades Boston did, both trades may end up being very good for both teams. If Fultz comes back and is good, Philly will be happy. When IT comes back, CLE is going to be just fine and they can add another piece with the Brooklyn pick so they should be happy. And Boston is of course happy with both trades for the most part (there are still the "we paid too much for Kyrie holdouts").
