I have a hard time seeing them holding off even if a new arena gets done. I mean we are second to last in attendance! Sure that would change if we started winning. But it is virtually guranteed to change immediately, no matter what, if they move, and the team will keep improving if they do. They might not even be able to afford to pay a full slate of good players if they don't move. The business is BLEEDING money. Even if they get a new arena deal, it'll take two years to plan/build it. And then you're back to needing to start winning just to stop the money bleed. Or, you could move now, perhaps get back in the black pronto, and all the while your team continues to get better.
I'm almost rooting for them to move just so that it'll help the plight of the team! I guess you could say I root for the name on the front of the jersey, the home jerseys that is.
Then again I moved away from sac 16 years ago, so my perspective is different.
