Sham has said that Shelden Williams has a guaranteed minimum salary of $825,000 roughly at least what the C's have to pay.
Sweetney has the same salary but it is not guaranteed and would not be until a date in Jan. when all contracts for the year are guaranteed.
Hudson's contract is for about $450,000 and likely is not guaranteed.
I think Hudson is safe unless another pg is added and he looks pretty good.
Williams doesn't but my guess is another team would take a chance on him, so Boston could probably get a team to agree to claim Williams, which every team can do and it isn't like another team could get him cheaper by letting him clear waivers.
I wouldn't be shocked if Boston decided to move TA, Scal, and Giddens for Antonio Daniels, who is going to get bought out if he isn't dealt. He is a solid veteran guard who would also give Boston one 6+ mil expiring contract at the deadline instead of trying to trade someone 3 guys midseason.
It isn't worth doing this to keep Sweets but it might be why he is here.
