Another rumor that is 99% certain to be bogus, but just because I want to say "you heard it here first" if it actually manages to happen, here it is:
Radio reports out of New Jersey had a package being discussed as: Kidd and picks for Welsh, Mihm, LaFrentz, and Banks.
Got this off a Celtics Newsgroup and I cannot vouch for the credibility of the poster. Reasons for the C's to not be interested in this are many: Bad knee, bad contract, bad relationship with Boston fans. Reasons the C's might be interested: its Jason Kidd. Do with this what you will.
