NJ is over the cap. No team over the salary cap may do a sign and trade as of year 3 under the new CBA. There is no way he can go there. He can't sign outright. He can't be signed and traded there like say LA did with Nash via Phoenix. The lakers used the CBA to its advantage because signs and trade won't be there next year for the nets. Dallas is the only place he can go but they have never signed a big free agent ever and the core isn't better as they would have to let go of everyone else but Mayo, Marion, and Dirk who have multi year deals as a max with Dwight plus them would put them at the cap.
You do realize who the Nets owners is right? And how a little fine for being over the caps is a slap on the wrist for him.
