I don't think many changes are needed. I think bringing back most pieces is really important, as well as giving a health Dwill and Lopez a chance with this team. Re-sign Pierce and AK47, let Blatche and Livingston walk.
Orlando has no reason to keep him. Earning 7.5 million next year, Orlando is rebuilding, and with Oladipo emerging, as well as the Magic having the #4 and #12 picks in this years draft, they will have young players that will need to play and gain experience in this rebuilding process. Nets get a great all around player. Afflalo defends well, shoots the 3 ball well, plays hard, everything you want. Something this team needs.
