Some Notes:
2025 pick can be traded. 6ers own worst of theirs and Houston. Fanspo has some of the picks.
This trade is a deadline idea, so signing issues would not actually be a problem.
Nets
The Nets are still trying to win around Bridges and their depth. To do that, they need to add pieces so that Mikal can take real shots before 30, otherwise their window will start to close. Brogdon is a great floor general and spacer that they so desperately need. Dinwiddie probably isn't a championship caliber starting one. Jerami Grant would be a big addition as a high level 3&D combo forward. This would flat out make them better now for at least a handful of years as JG is 29 and Brogdon is 30 (probably 4 or 5 good years left). You also get to clear Ben Simmons horrid contract clogging up your roster and making competing very difficult in the short term.
Blazers
These are the guys who don't fit the timeline, so have to move them anyway. I think it makes a lot of sense to get paid two picks and a rook in exchange for two win now players and taking the worst salary in the NBA off their hands. When it expires, it will create $40M in cap for the Blazers to play with/extend their key guys. I'd particularly like to bet against Phoenix and while their 2025 pick might not be that good, there's a good chance their 2027 pick is really really good imo.
