Bucks take on Beal but land #2, Barnes and young wings to build around. Beal and Lillard can be vets who will mentor Dylan Harper, before getting moved on next offseason (Beal may need to be bought out if he can't raise his value?)
The Raptors now build around a core of Quickley, Dick, Ingram, Giannis and Poeltl. They give up a lot of their young role players but they are instantly a top 3 side in the East, and may even be favourites to get out of the east next season.
The Suns lose KD and don't get their picks back, but now have a very balanced group of players to add next to Booker. (and the FO save money) A starting lineup may look like Booker, Barrett, Vassell, Dunn and Portis? That is very versatile and there are still the likes of Allen, Richards, O'Neale, Kuzma and Ighodaro off the bench.
The Spurs swap Vassell for KD by moving back from 2 to 9 in the draft. They may land 2 of Maluach, Essengue and Bryant, who would all fit in very well with this roster.
From a Bucks view, we take Harper and now have a heap of defense and shooting to put around him. Barnes and Beal will also take the load off him and be the "main guys" while Harper finds his feet in the NBA.
If you wanted to start Beal, a lineup could look like Harper, Beal, Walter/Agbaji, Barnes and Mogbo/Sims (Centre would be a position I would target in Free Agency)
Ideally Beal would come off the bench and I would start Harper, Green, Walter/Agbaji, Barnes and Mogbo.
I would love to find a way to acquire Kuminga via S&T, or even send Pat C (expiring deal) to the Bulls for Pat Williams and his awful contract. I see these two players as potential 5's moving forward. Switchable wings who are strong enough to guard most bigs. lineups with either Williams and Kuminga alongside Barnes, Mogbo, Agbaji, Walter and even Harper would be hard to score on.
