Is he a perfect player? Of course not. But he was almost certainly this particular team's most valuable player.
I just haven't seen any convincing argument for this being true. Is there any evidence to suggest that the team actually performed better -- offensively OR defensively -- with Jeff Green than without him, for example?
Just taking a look at ESPN's real plus minus rankings, for example, Jeff Green ranks behind most of the regular rotation players on the team this season, including Phil Pressey and Gerald Wallace.
Jeff Green did play in all of the team's games. He has that over Sullinger and Bradley. He also led the team in scoring. He hit that nice shot against Miami, which was probably the high point of the season for many fans. He has that going for him too.
I'm just not sure how much of what he did on a nightly basis actually made the team any better than it would have been without him.
See, lets see if we can walk through some logic here.
a) This team sucked. However one might argue the merits or flaws of individual players, and whether it was through talent or organizational intent (coaching & personnel decisions) or a mix of both, there should be no argument that this team sucked. It had a W-L record of 25-57. It scored a miserable 7892 points and gave up 8258.
b) Based on point (a), it is likely that during the vast majority of floor minutes of this season, the team was negative.
c) Green played 2805 of those minutes (16th most minutes in the NBA). Far, far more than anyone else on this crappy team, but nevertheless, sharing the floor with various crappy combinations of this crappy team executing a gawd-awful crappy offense and trying to play defense without a real center.
So ... we should hold it against Green that his floor time +/- is negative?

The facts are, when Green was allowed to actually _touch_ the ball, we were more likely to generate _points_ than when anyone _else_ on this team touched the ball.
But for whatever reasons, we did not allow Green to touch the ball very much.
