The great unknown here is what plans, if any, Ainge has for the cap space for 2012. How committed is he to maintaining that? We all assume he wants cap space, but how much?
Would he be willing to offer the full MLE on Deandre Jordan?
Would a Sheed-like deal (paying two/three years of non-guaranteed full MLE) be enough to get Kenyon Martin?
I wouldn't be surprised if Ainge looked overseas for a big man, either (although I have no idea who's out there).
As I've stated elsewhere, I don't agree that the team has to be blown up. It's still very much a contending-caliber roster, but it does need an infusion of new blood. Ainge has his work cut out for him.
