I'm not convinced Noel gets you two first round picks unless they are back of the draft. He's an absolute zero... Actually huge negative on offense. He is an excellent defender though.
I don't think you can play them both together. Embiid would have some range to his game for that to work.
I think you'll see Embiid headline a package for a star in a year or two. There were some Embiid trade rumblings at the deadline which leads to the belief that Philly isn't sold on him.
