I actually think Lue has a better chance of getting traded, on two levels:
1) His perceived value is higher. He's had championship experience with the Lakers, he's played at a relatively high level as a starter in Orlando, and he's consistently shown that he can sparkplug a bench with good three point shooting as well as the ability to create his own shot, and even hit it. Not a scoring machine, but think Eddie House-like in his ability to spark the bench. Although he's not a real passer, he's not turnover prone at all either. He hasn't really had much of a chance to play for a contender, but his game definitely looks the part as being a missing piece for many teams.
2) Although Lue can be a source of consistency off the bench for us...think about it...does a 30 year old vet like him really want to play off the bench for us, behind Udrih, on a very mediocre team? He's accepted it in Orlando, but him being a relative journeyman in this league I don't think he's willing to accept that sort of role for long, unless it's for a winning team. Besides, he's sort of redundant to Quincy Douby, and if he stays it will undoubtedly take away playing time from Douby and we'll get stuck into playing veterans for a mediocre team--a trend I at least I'd prefer not to follow. Playing youngs for a mediocre team would be better--hence Lue would probably be better off geting traded.
I would imagine we can even get a 1st round pick for Lue, depending on how badly a team wants him (I would imagine Phoenix would dangle one). His talent relative to the amount we can get for trading him suggests a late 1st rounder, but even a 2nd rounder should be fine.
