Eddie Curry hasn't sniffed a court in a very long time. He's in aweful shape, and even if he weren't he's not a good fit for an uptempo team. He's a poor rebounder, and requires many touches to be successful.
Now I know this is GSW we're talking about, but it's not realistic to imagine ANY team trading for Curry any time soon, much less the Warriors for Jackson who is a productive player (15 assists the other night).
So I see three problems here:
1) Curry is untradable;
2) Add Murrow in and it becomes laughable;
3) Why do we want to help the Knicks achieve their goal of cap space enough to load up around LeBron next summer?
LeBron, I am convinced is ending up in NY or NJ/Brooklyn next year. He'll be there no matter what we do. But if we can add Jackson, keep him away from Cleveland, and add a future star in Morrow(sorry, that's the way I see him. If he starts for the C's in 2010-11 with Rondo/Pierce/KG/Perk he will become almost All-Star level), we help our club tremendously. It would still be tons better than any team NY could throw together with LeBron on it for the foreseeable future.
I still see no explanation as to why the Warriors are giving up the two best players in the deal -- in one case a very talented young player on the cheap who fits their system perfectly -- for junk. It's not realistic to imagine Curry being traded for a very good NBA player, or even for an expiring contract. He's not an NBA player anymore.
Meanwhile, to yours and Wdleehi's point, performing this trade doesn't allow the Knicks to get LeBron; it allows the Knicks to get LeBron and sign another high-priced free agent. If you actually believe there's no difference between this (Lebron and another All-Star -- say Joe Johnson or Chris Bosh -- playing for a top NBA coach on a team where other FAs will line-up to take the MLE) and LeBron staying in Cleveland with Sideshow Bob, Boobi Gibson, Mike Brown, a poorly constructed team and ltd cap space, I'd encourage you to think again.
Thankfully since no NBA franchise is foolish enough to trade for Eddie Curry, we won't have to cross this bridge.
