*Note - in this deal, I think Fournier could be a fluid piece, who could end up in SAS or LA.
LA get LeBron his 2nd star, and get to keep Kuz and Ball. They could opt to take Fournier back, instead of SAS taking him, but that would eat into their cap space for chasing other big name FAs. However, Fournier could be a great fit with Kuz + LBJ + Beal, or he might be a piece they can flip to teams like HOU or MEM who are shopping expensive PGs and other pieces.
WAS, not being a team that likes to tank, get an all-star in return, and a boost in youth with the #4 pick (to go along with their #9). They also get to clear Mahinmi's contract off the books.
SAS get younger, with a potential future stud if Ingram is healthy. They also get a player who would fit Pop's system well in Fournier, and a decent pick.
ORL get a new starting PG, plus some young bench depth. They absorb Mahinmi's deal for a season, and he becomes a stop gap C whilst Bamba keeps filling out, which allows them to cut Vuc + Ross free and chase other backcourt additions, like Russell or Brogdon.
Trade: DJ to ATL or PHO for cap relief.
Renounce rights on Vuc, Ross, and everyone else needed to get us to $28M cap space. Stretch Moz.
Sign: D'Lo to a max. If the Nets match, sign Brogdon for much less (but too much for Milwaukee to want to match. Maybe an AG type contract?).
Now, we don't have to keep all this youth. We could flip some for some stable veteran hands. But the youth we're adding at least come with a few seasons experience under their belts, and White comes from a winning team. Russell or Brogdon would help provide veteran stability, too.
