The Lakers have signed 31-year old power forward Troy Murphy to a 1-year deal.  Murphy played in 35 games (4 starts) for the Celtics & Nets last year and he averaged 13.3 minutes, 3.1 points, 3.2 rebounds and 0.7 assists per game.  He has now played in 656 games (481 starts) in his NBA career and he is averaging 28.5 minutes, 11.8 points, 8.3 rebounds and 1.6 assists per game.  Murphy is an outstanding shooter for a player his size as he has made 38.9% of his shots from three point range in his NBA career.  If healthy, Murphy is going to really help the Lakers off the bench.
