DET

Pistons can add Reaves and maintain their elite defense. Playing him as the #1 with Cade as a big guard, and Ausar on the wing works. Add in Jenkins as the sixth man, and the Huerter/Harris/Holland contingency on the wing and the Pistons maintain their size and defensive advantage while adding another real bucket getter. Gafford is obviously a downgrade from Duren but he is definitely preferable for a third of the price.

LAL

The Lakers strongly upgrade in the middle for Luka. Duren isn't the rim protector that the Lakers would most prefer, but he's much more of a consistent offensive rebounding threat then Ayton or Hayes. He'd thrive in the pick-and-roll with Luka, much as he does with Cade. He'd immediately be the biggest guy on the floor for the Lakeshow. Losing Reaves isn't great but they need to start building a more sensible roster for Luka.

DAL

The Mavericks get a pick 25-30 this year and a first rounder two years from now. Neither are great assets but considering how little capital teh Mavericks have, adding picks and getting two years closer to clearing the books is preferable. Let Masai rebuild this team around Flagg. Most everyone over 27 should be sent packing.
