I think it's a fantastic trade for both sides. The Mavs give up wing players, of which they have many: Morez, Aldama, Flagg, even Klay. They gain a super athletic outside playmaker with great potential, while Portland gets rid of one of their many guards, since they already have Ja, Lillard, Jrue, and Scoot. They also gain two wing players with great shooting skills, which they desperately need, as both Ja and Advija need spacing, and PJ and Marshall could provide it. I want feedback. Who says no?
