The only possible team in the top 4 that Rondo would consider signing extension is the young and upcoming Orlando Magic. Trade Rondo and Anthony for Afflalo, Nelson, and sway our #6 pick with their #4. With #4 we take 6'6 PG Dante Exum or one of the top 3 if they fall. Magic get rid of Nelson's salary while Celtics only have one year left on his deal to serve as mentor for Exum. Afflalo is big upgrade at SG and allows Celts to have Bradley come off the bench if they re-sign at reasonable number or do S&T. By signing a draft pick it is much less costlier that what it will cost to re-sign Rondo thereafter freeing up more cap space for other deals. Use Sully, Bass, Bogans, and two first round picks to get Love. Sign Pierce for MLE. Get Asik for TPE and draft pick. S&T for Free Agent Carmelo Anthony using Rondo cap savings and giving Knicks Green, Wallace, and two first round picks. For these moves have used up 6 of the 9 draft picks (need to keep 2 to meet every other year requirement).
PG - Exum, Nelson, Pressey
SG - Afflalo, Bradley, Babb
SF - Anthony, Pierce (MLE), Johnson OR
PF - Love, Olynyk
C - Asik, Faverani, Iverson
This team is similar to first Big 3 when Celts had 3 stars and a young, promising PG.
