No player is getting moved this season. This team doesn't need anything except to wait to round into form.
What happens with this roster after this season hinges on the result. If we lose before reaching the Finals, Brown, Rozier, Smart, and the 1sts will be on the block. If we win/lose in the Finals, we run it back with this roster sans Rozier.
I think a package of Brown and Rozier would've gotten us Kawhi, Butler, or George and if combined with the 2-4 1sts could be enough for AD (if things sour in NO (which is the only way they trade him)). Other than that or another superstar, trading Brown with the progress he's shown and still on his rookie contract would be foolish and unlike Ainge.
