Bucks
The inevitable has happened. Giannis will not stay, so they should capitalise on it ASAP.
They get 4 young players of different calibres. 2 future starters and 2 potential franchise players.
They get their 2 picks back (if the Bucks don't trade right, those become extremely valuable)
An extra 2027 FRP for good measure
Lineup: Rolins, Harper, Vassel, Sochan, Hansen
Blazers:
Well, they get Giannis. They have what the Bucks don't: A high-quality supporting cast AND assets to make it even better. Currently, Deni is carrying the injured team to the 9th seed. Giannis with a full roster can get them to the finals.
Spurs:
Wemby is ready. The Spurs shouldn't wait.
Deni is the guy. If I had to pick 1 player for them it would be him. They need everything he brings: The wing scoring, the rebounding, the playmaking, the fast breaks, the spacing, the wing defence, they need it all.
Grant is a superb addition as well, great wing 3&D - Elite shooting and defence - currently a strong contestant for 6MOTY.
