I think Sully for Shumpert is a no, but what about;
Boston sends Humphries, Wallace, Brooks and Lee and Knicks send Stoudemire, Shumpert, and a couple of their cheap free agent signings like Aldrich on Dec 15th.
It chops about 5 mil off our payroll this year but we don't get the Humphries expiring next. Then again, we get out of Lee and Wallace on that third year. Amare would be a big expiring for us next season.
