Honestly Portland realized that they won't be able to do anything in Dame era, and looking to find new and younger players to build around a new star. They will need great players coming up draft, first it can't be a superstar right away, would be very hard to get number one pick this year for example, there is a huge expectation out of Wembayama and if they can get him, then they could build around him.
I would say the smartest thing Dallas could do this year would be that for example, get the first pick, give WHOEVER they want outside of doncic, that's it, get Doncic and Wembayama on the same team, or for Portland Dame and him again, would be great improvement.
