There's a way to get this trade done to get Josh Smith without renouncing our free agents, if we recruited a 3rd team and it needs to make sense for all 3 teams involved.
Boston and Atlanta are over the cap.
If the 3rd team let's say the Nets sends Petro and Farmar (expirings) making 7.75 million combined, Boston send Bass who get's S&T, he would probably earn between 5-6 million in his first year.
We give the Hawks 21 and 22 to make it happen, Atlanta would have back to back to back picks.
Boston sends Atlanta cash 3 million to buyout Petro.
Boston could still resign their own free agents and have cap space next summer if Pierce and KG retires, and Smith expires.
Both Smith and Rondo recruits Howard next year and Smith takes less so Howard signs a max contract, all that and we can keep Green I think if he signed a cap friendly contract.
However Nets need guys signed since they're way under the cap and Farmar and Petro aren't bad contracts (expirings) so they would probably want a 2nd, hopefully Atlanta gives them one.
Boston shouldn't give up more than 2 firsts.
