Not sure about this one. Philly may want to save their pick capital or get out of the business of injured superstars, but AD seems generally more available than Embiid and PG the last 2 years.
The East is pretty open. If they can get partial seasons out of AD and Embiid, they could be nasty to play. Embiid is basically a very, very tall shooter now, so he and AD can manage spacing issues. AD can still roam as a help defender. They can spare one of their guards.
Maxey - VJ - Oubre - AD - Embiid
The Mavs get shooting and guard play in the deal, plus a very nice pick. Maybe MPJ and PJ Washington are too overlapping for this to work, but I like giving more spacing for Flagg. Grimes comes back to Dallas and fills a big need.
The Nets get a pick and prospect by trading out of one bloated contract and into a more bloated one.
