This is the 1st time that the Blazers have started to try to build a contender team around Dame. At a minimum, we should give them 2 years of building talent, coaching team fit on O and D, and allowing the best Dame ever to excel with a coach that was a Champion at his position.
Even thinking of the time to consider trading Dame should wait until Dame is 36. Some of the comment in this thread are 4+ years too early!
Any thought of trading Dame before expiration of his contract in 2027 seems destructive to the future of the Blazers, and highly likely to end the interest of most of the fans (and thus the financial feasibility of the Blazers in Portland).
Let's wait at least 2 years and see whether the new build around Dame era can produce an NBA Championship. I think it is likely!
