Grizzlies obviously not content with the perimeter shooting / shot creation on their roster. Going after JJ signals a certain degree of desperation. Could be a solid fit there, though.
If the Nets can get a pu pu platter of role players for Joe Johnson, that would be bad news for the Celts, because all the Nets need to guarantee 35-40 wins is some competent depth and to re-sign Young and Lopez (which seems likely).
i am not sure i see your concern here. if indeed the nets ship out johnson, one of their better players, and only receive a heapin' helpin' of crap in return, how does this improve their team?
further, i dont know how the nets can ship out that much salary and NOT take some salary back. given that they nets are already in salary cap hell, i am not convinced this deal provides them with better talent, provides them with salary relief, or provides them with both.
i would be happy to learn more though since i am not that well acquainted with the nets situation.
