Before you say Blazers pass, hear me out. Yang Hansen hasn't done much and has only played 22 out of a possible 40 games. Yang also is young and can still develop, which would make him perfect for Denver so when Jokic starts to regress, Hansen would have developed enough to take the starting spot. This scenario would only happen if he stayed in Denver for another 4-5 years. Before you say anything about not trading young players, you all didn't hesitate to put Tre Johnson, AJ Johnson and Cam Whitmore in Trae Young trades.
For portland, this gives them a proven center who wwould start quite a bit given Robert Williams III struggling with staying healthy. The Blazers can even flip Jonas in a larger deal and try get someone better like Nic Claxton, Deandre Ayton, WCJ or someone else.
