I think I have talked myself in to a total rebuild on some conditions.
1) you need to get a top 5 pick this year and one more,
2) you need to get at least two extra 2014 picks (with own 3),
3) you need to get back 1-2 players in the mold of Fields or Amir (< 25 years old proven role players that are highly efficient players).
4) you have extra cap space for 2014-15 season to be a facilitator in deals or take on salary for tax fearing teams (for a price).
It is not very often a team enters in to a rebuild with the hardest piece already in place - that of course being the C and JV.
