Shira Springer says there is a remarkable turnaround in Boston.  She reports in the Sporting News that Antoine Walker has done conditioning work for the first summer ever, and appears ready to show up in camp about 12 pounds lighter than last season.  Paul Pierce has undertaken a rigorous weight lifting program this summer, so obviously will be in better shape than after he was stabbed last year at this time.  Milt Palacio has added definition and muscle.  

Perhaps most remarkable, Kenny Anderson is working with a personal trainer in Atlanta.  Add all that to Jim O'Brien coming into camp as the permanent coach, and there is increased optimism in Boston.
