Wallace not ready?

Despite being on the Knicks' roster, Rasheed Wallace's contract will not become guaranteed in full until January 5th.  Wallace is expected to miss the entire preseason as he works on his conditioning and as of yet he hasn't been cleared to practice or scrimmage due to his lack of conditioning.  With that being said, if his conditioning doesn't improve, the Knicks could waive Wallace before January 5th and that would allow them to only have to pay a prorated amount of the $1.3 million that he signed for.
