Anything they do would have to involve a trade. We don't have money for free agents and this is supposedly a crappy year for free agency anyways (at least that's the reason given for why nobody wanted to trade for Grant Hill's expiring contract.)
The big thing is resigning Sasha after the season. That's a huge priority. Otherwise we're worse than we are now.
And if they can't sign Varejo back, then they need to address the fact that not only is our front line mediocre, but it also has no depth, unless you count Pollard as a viable option (I don't) or Mike Brown gives Dwayne Jones a shot to play.
I would really hate to part with Gibson in any trade. He's shown flashes of being a pretty good scorer.
I also wouldn't want to trade Shannon Brown until we get a chance to see exactly what we have there. He was rated really well coming out of the draft, but for some reason Mike Brown puts him in and expects him to be able to contribute in 3-5 minutes before being pulled out of the game again.
Of course trading Lebron is stupid. You'll never get equal value for him.
Anyone else is pretty much fair game, although I wouldn't part with Z, unless we got something really decent for him. I still maintain that Z is a very talented big man who is ill used more than anything else.
I would love to see us be able to swing Z for Tyson Chandler and someone, but I don't see Z fitting with the Hornets all that well either. It would be nice to get a big man that isn't afraid to dunk the ball though.
