Taking a break from the Celtics after this post....
Brad Stevens is paid a lot of money to manage this roster, he up until this off-season has done a wonderful job. Foresight and projection are a large part of the job. Projecting future prospect development, projecting future drafts, projecting player salary, projecting teams cap, and projecting other teams future moves. While Brown's trade may very well prove to be a projection into the future (2028 draft, future FAs, and Brown's future extension) it is a failure to project that has brought this terrible trade return.
If Brown's future extension was a big enough worry to require this trade than he should have been moved last off-season. Would ATL have traded Brown for Alexander-Walker and the 2026 Pelicans pick that ended up being #8? Prior to his amazing Rookie season would the Hornets have traded Kon Knueppel and picks for Brown? Hindsight is 20/20 but when you are paid 10+million per season to predict the NBA future I expect better..
