Pelicans- they bascilly have no real good big man depth, signing DeAndre jordan shows that they know they don't have any. One of Poole/Murphy/Jones will have to sit once Murray comes back as well.
Bucks- For Milwakee, Its simple, trying to get a championchip in win now mode for Giannis is the plan, here they make a move that fixes their problem of guarding on the perimeter. they might just be the 2nd best defensive team in the Nba with this trade.
Nets- Simple for them as well, build on draft capital in their rebuild, addtionly, Kuzma's contract ends in 2027, where the FA class is stacked.
