Interesting. There would be no reason for him to be in Boston right now (buying TOYS no less, somewhat permanent home-ish items) if he wasn't planning on coming back/staying, but we'll see.
Well, Sheed has done a lot of charity work with kids, so I wouldn't be the least bit surprised if the toys were for a school or something.
I think it is interesting that Sheed is still in MA, since he reportedly wanted to return to Portland, but I wouldn't read too much into it right now. He may be just be tying up lose ends before moving back out there before the school year...or something completely random.
My guess is there is little connection between the Celtics, and Sheed still being in Boston at this moment...especially since many veterans live in different cities from where they play during the summer anyways. If he is here, it likely has more to do with his life more than his basketball career.
At this point, both Danny and Doc have gone on record saying Sheed plans on retiring. Until a credible source (not some reporter speculating) reports otherwise, that is what I am going to assume is happening.
