Philly is slotted at 3 and there's a good chance Embiid is the guy available at that spot. Does that make Noel available, as he plays the same position? What would it take to acquire him?
This could be an interesting avenue to go if trading for a star (Love) is not an option.
A move like #6 for Noel + #10 could make sense for both sides.
The BPA at 6 may very well be Randle, who is a terrible fit for Boston, but who could look great next to Embiid.
Meanwhile the Celtics get a rim protector who could work nicely next to Sullinger or KO, and at #10 a player like McDermott, Saric, Gordon, or Harris will be available to add some talent on the wing, which the Celtics really need.
