the Bulls have acknowledged having an interest in that type of player(Paxson was careful not to mention Gasol by name, iirc). Reports have surfaced as to the type of offer the Bulls might put forth...
eg. PJ Brown, Ben Gordon and a pick(likely NY's pick), some of the rumors have mentioned Luol Deng.
I think the Grizzlies would have interest in Monta Ellis and West did like Mickael Pietrus. I also think Tyrus Thomas would fit well in Nelson's uptempo attack... hence the hypothetical trade scenario.
This deal gives the Grizzlies MAX cap space(PJ and Eddie Jones off the books) this summer, a young PG for the future in Ellis and a half season to audition Pietrus before he hits restricted free agency. The Grizzlies also pick up another potential lotto pick in what should be a solid draft to go along with their own pick, which could be top three.
