If we are not spending money on a big free agent or two, I'd prefer to see Ainge dismantle most of this team and build up the team through high draft picks.
I wouldn't necessarily be against that, although it would make this past year feel like a total waste.
Dismantling this team would mean, what, though?
Trade Sullinger and Olynyk for unproven young bench guys and / or late 1st round picks.
Dump Bradley for a 1st rounder (or, ideally, use him to move up in the draft).
Trade IT for a pick or two.
Give lots of playing time to the four or five rookies they draft this summer plus James Young and Smart.
Look into trading away Zeller for a couple younger players with higher upside but no proven ability.
Dismantling what they have now isn't going to help you much besides ensuring that the team loses more games. You're not going to get any superior future assets by trading away any of these guys.
It also might actually drive Stevens to consider a different coaching opportunity, since he seems to really want a consistent group that he can build over time.
