He should ask NJ to trade him.
However, any team that trades him should know, he is going to opt out and remain non-committal. However, depending on the team, I'm sure some would feel confident they would resign him.
Then, Deron simply leaves that team high and dry next summer and goes back to NJ, having gotten us additional assets in the process.
He also tells Dwight he should do the same thing. Be willing to be traded to another team like LA, so they are stripped of assets, and not actually re-sign with them.
Deron gets traded to Dallas, who obviously thinks he will stay.
We get Kidd, Odom, Terry, Roddy B., #1 for Deron, Farmar, Petro, Shawne W.
Dallas thinks they made out like bandits.
Dwight gets traded to LA for Bynum and maybe Gasol. LA gets their guy and thinks all is good in La La land.
However, both leave their respective teams and come back to Brooklyn having ruined Dallas and LAL!
Deron W. / Roddy B.
Brooks / Morrow
'12 #1 / D.James
Lopez / Jordan W.
Howard / HOU #1
And then to make things even better, players like Odom/Kidd/Terry decide to stick around for the MLE or minimum contracts since they like the team so much.
