Trading Rondo signaled the start of serious "rebuilding". I think Ainge tried to "build around" Rondo but that didn't work. I think we are rebuilding more gracefully than NYK or PHI, at least so far. Call it tanking or whatever you want but we are now doing it.
Second, I think we have enough draft picks, at least for 2015 and 2016. Unless the draft pick is a sure fire top 10 pick or something like that, more picks are not going to help.
I really don't see us doing much of anything. Maybe the likes of Bass or Thornton can be traded for younger players but since we don't need more picks, these trades seem unlikely to improve us much. (Trading deck chairs for deck chairs).
It is going to be a couple of years of collecting assets I'm afraid which means no playoffs likely. I think Ainge will look closely at fairly priced FAs who can be locked up for 3-5 years (as assets) but I doubt we will end up with anyone big this off season. It would not surprise me to see Ainge spend some money on 2nd or 3rd tier FAs that are a good value.
