I'd be tempted to give Kurt Thomas a year if he's available. They don't need to hit a home run right now. I don't want to see money thrown at a defensive-minded C for the wrong reasons, meaning as a band-aid for the overall defensive woes and/or as a means to making things work with Bargnani. Just improve the overall defense and look for our bigs to get a little stronger.
Nabbing another draft pick would be nice.
