Well, Danny Ainge tried to trade him every year Rondo was there.

You can see the logic in the Nets making a win now move but it was absolutely indefensible to put no protections on any of those first rounders. KG and Pierce were hitting their upper 30’s and you had two injury prone guys in Dwill and Lopez. It didn’t take a crystal ball to envision them in the exact situation they’re currently in. At the very least the last 2 traded first rounders should’ve had top 3 protections. 99% sure Ainge still says yes and if he demands they be unprotected then don’t make the trade.
