CelticsStuff Live has 3 reports from the Season Ticket Holder's Picnic posted on their site. Kim Malo's report gives a good description of Al's new physique.

I can certify from live and in person that Al
definitely looks in great shape. And for those bemoaning the loss of
bulk to throw around on the boards and in the paint, I’ll add that
it’s clearly muscle based cut and not just a matter of dropping
pounds - he’s not skinny, he’s lean, and there is a real difference.

The only memorable moment was when Telfair guarenteed the playoffs this year. That was great to hear but big talk from a guy who may not start, however it appear that he is stepping up into a leadership role as Allen and Rajon deferred to Sebestian during their portion of the Q&A.

I managed to get some conversation with Doc.
I asked him about Tony Allen’s knee. He said that Tony’s knee condition was chronic and he would have “bad days” for his whole career.
He contradicted himself though saying he hadn’t lost his athleticism. When I questioned this he said: “except on his bad days.”
I was also concerned about Wally. I asked him if he was considering using him as a sixth man to save the wear and tear and he said he was, but that Wally was healthy now. When I reminded him that Wally had all or most of his cartelage removed after hi freshman year at college, he said something about his good days and bad days, also. I really hope Doc takes this seriously. I not only want Wally being able to finnish games, I want to see him fresh enough to contribute in the playoffs.
Clifford Ray was pretty candid, agreeing with me that Jones and Pittsnoggle would compete for the last roster spot.
Armond Hill stressed that Jones was one of our tougher players and that Pittsnoggle was having trouble defending.
