I think it's shortsighted to trade PJW. The consensus for most of his time here is that he's our Aaron Gordon. I don't just trade that type of player away on a whim.
The simplest and easiest way to balance the roster is trading Gafford. The most basic trade that works is for Coby White.
It allows the Mavs to add a 15th player (Kai Jones) and stay below the second apron.
White | B. Williams
Klay | Christie | Hardy
Flagg | Naji | Martin
AD | PJW | Omax
Lively | K. Jones | Powell
Kyrie - Out
Edit - I'd also look to dump Hardy for anything and bring back Exum.
