People really aren't being fair at all in this thread. Walker left a horrid Atlanta team and jumped over to a mediocre Boston team midseason, and managed to turn Boston into a good team, a legit playoff team, and, some said, a team not uncapable of pulling of an upset or two against the better teams in the east. Sacramento has turned into a mediocre team in the deep west. There are two stances to take here: go young and build for the future or aquire old vets and keep the team alive. Most people seem to think that these are mutually exclusive, and that aquiring Walker in a sign and trade for Mobley (pretty much the only way we can get him) will prevent us from building. That is completely false. If we let Mobley walk, we will continue to be over the cap, thus unable to attract young free agents. The alternative that everyone keeps bringing up is trading for Nene. Denver has said no to that. So people don't want to get Walker because he makes us feel bad about the team, knowing we won't win a championship. Here's an idea: trade Cat for Walker, let them team stay in the playoff hunt. Walker gets some (undeserved) praise for filling Webber's shoes (he won't, but this is the media talking here). Some none too bright in the Isaih Thomas mold GM hears all this, and when brought an offer of Walker for some young talent, jumps at it. Look! Youth! Or, he actually pans out, does some good stuff for the team, we pick up a good SF and become contenders again.
Alternative: we do what the fans want and hold out for Nene. Denver still says no. Cat walks for nothing. We miss the playoffs, are over the cap, and our only trade pieces are Peja, Mike and Brad. With a team like that, there are no trades to be pulled off to make the team better. We enter the lottery, the new "promised land" of Kings fans. Celebration ensues. The team sucks and spirals back into the abyss of insignifigance in the NBA. Congratulations. Aren't you glad we didn't get Walker?
Honestly, for everyone saying we need youth, no one has any vision for how to add it. I have yet to hear a better idea than grabbing Walker and letting the situation play itself out, taking stock of the team in a couple months, and decide where to go with our 4 (Four!) very attractive trade pieces. Hell, if we package Walker we might be able to get rid of the behemoth contracts we got for Webber.
