What's next?

Once unrestricted free agent James Posey signs a new contract (probably with the New Orleans Hornets early this week), then you can expect more signings to follow. Other free agents have been slow to sign because they've been waiting to see what kind of deal Posey receives and from whom.
Later in the week, you can expect the Lakers to let restricted free agent Ronny Turiaf walk, refusing to match the four-season, $17 million offer sheet he received from the Golden State Warriors. It's just too much for the Lakers to spend on a backup.
Once they let Turiaf go, then the Lakers probably will focus their efforts on signing a replacement. As previously reported, they could sign free agent Jorge Garbojosa, a 6-foot-9 power forward from Spain who has played with the Toronto Raptors. Kurt Thomas also could be a possibility.
The Lakers also hope to re-sign restricted free agent Sasha Vujacic. Talks are ongoing, which you can take to mean that Lakers general manager Mitch Kupchak and Bill Duffy, Vujacic's agent, are still a ways apart on a new contract.
No other team has stepped forward to make Vujacic an offer, so the Lakers' hopes to get a deal done soon are very much alive. This could be the week that everything starts to fall into place around the league.
