ok, time to dial back some of the more wild trade ideas, and try a good ol' lateral move:
spurs trade: elson, 2008 2nd round pick, cash (300k-800k)
spurs receive: patrick o'bryant
warriors trade: patrick o'bryant
warriors receive: elson, 2008 2nd round pick, cash (300k-800k)
why for the warriors: pob is out of the rotation, and has been for most of his career. nelson seems to have no desire to give him any PT, and the organization has seemed to give up on him (declining his option last summer, making him an UFA this summer). elson probably wont see anymore time than pob, but at least he is slightly more productive. the real reason for this would be to acquire the pick while giving up nothing.
why for the spurs: elson may very well be out of the rotation, so the downgrade to pob is of no concern (especially if ian replaces elson as the 4th/5th big). the real reason for this move is the 750k or so this deal saves under the tax line. correct me if im wrong, but that would be enough wiggle room to immediately sign a minimum player for the rest of the year (richardson?). so this move doesnt thin them any more at the 4/5, while giving them the ability to sign richardson now (or whoever else they want) for the rest of the year without having to go over the tax line.
