ANALYSIS: With the departure of Gordon Hayward, signing free agent Paul Millsap would certainly strengthen the C's roster and Millsap would provide a veteran presence for the Celtics locker room, which got hostile at times last year. Aside from leadership, Millsap has still proven to be effective at 35 years-old and is coming off season averages of 11.6 points and 5.7 rebounds per game.
