I think it would depend on how the Nets are doing. If they're having a horrible season (Lopez gets injured, etc.), and look like a lock for a pick in the top half of the lottery, then a Noel-for-Nets-pick framework could be possible.
The question then is, do we trade a chance at Simmons for Noel? I doubt it, but if the pick falls around #5, Embiid starts playing late in the season and seems like a good fit, and we don't like the players available with our pick, a draft day trade is a definite possibility
