actually, since NJ has been talking about moving up to take a PG or taking one at their first pick, effectively making him their 3rd guard, BBD, TA and a pick would probley do it. remeber that NJ didn't do the kid deal to be a contender, it did it to drop a major source of cap with lebron coming up in 2010.
while its a incredible longshot to be sure, its not like NJ considers him a star player, he's a bench guy for them. it wouldn't take a superstar, or even a starter, to pry harris away from them.
I fail to see how your analogy is all that accurate, while i agree the trade is extremely unlikely, if for nothing more than NJ won't want to help us out with our upcoming Rondo, ray and no one situation, i don't think its out of the realm of possibility.
