I'm gonna go on the far end here and throw this out there.
With all the free cap space we have, we'll pick up someone decent. A good quality big man is always good. We have a ton of them right now but I don't think Sammy will be here after this year.
If all goes right, we can be a great team instantly. If all goes wrong, we'll be in the same place we are now, the shit hole.
Every other free agent on the 2011 market are mid-level players, not great players with some exception.
