This comparing of Jeff Green to Pierce has to stop.
They are very different players, despite the fact that they play the same position. We need to expect different things from Jeff than we expect from Pierce. Jeff is never going to become Pierce.
Pierce is an all-time great scorer. He will know how to score until the very last day he steps on a court. For his career, Pierce has averaged 21.5 points per 36 minutes, on 15.8 shot attempts and 7.2 free throws. Jeff is an average scorer who can exploit matchups to go off at certain times. For his career, Jeff has averaged 14.9 points per 36 minutes, on 12.6 shots attempts and 3.5 shot attempts. Pierce's career high PER is 23.6, and his average PER is 20.6. Jeff has never had a PER higher than 13.9 -- below league average.
Ideally, Jeff Green is a glue guy who will make some big plays and give you a nice all-around contribution without being the focal point. He's got a lot more Lamar Odom in him than Paul Pierce. That's not even a bad thing. We just need to let him play that role and not try to shoehorn him into one he's not suited for.
