Ok, so Osborn mentioned in a post earlier about the Knicks and Rockets kicking around a swap of Eddy Curry's contract for Jared Jeffries's weird little teeth and charge taking abilities.  So the big problem with this is the Knicks have a full roster, the Rockets are over the cap, and the difference in the players salaries is about 5 million dollars.  There are no mix of appropriate expirings on the Rockets roster, so a 3rd team will need to be involved.  Here is my proposal off the ESPN Trade Machine.  Third team is the Celtics and here's how it breaks down:

Knicks get: Jared Jeffries, Rasheed Wallace's expiring and waivable contract since he's retiring anyway

Celtics get: Trevor Ariza

Rockets get: Eddy Curry's expiring

So the Celtics get another player who could fit in, the Rockets dump salary which is good because with Yao likely done they'll need to change gears a bit, and the Knicks get to add Jeffries without disrupting the rest of their roster.  Maybe draft picks change hands, too.  This is pretty tame but I know there are trade machine junkies all over this blog.  This is a transaction that could get pretty weird/complicated so do your worst.
