I think Green's consistency (or lack there of) is overblown, irrelevant, and essentially a distracting straw man to take away from a player who simply is not very good.
Players will have variance in their game. Numerous numbers of NBA players have a few games here and there of high scoring and follow those games up with strings of bad games. It's not that the high scoring games show that Green is a great player who just needs to do that consistently, it's just that the hallmark of mediocre players is that sometimes they contribute, sometimes they don't, but over the long term, they average, well, average totals, just like Green has for all 6 seasons of his career.
I think that's a dismissal of an argument that pending further analysis (most notably a larger sample size) could illustrate a very valid point.
IE that Jeff Green's variance in scoring helps support a claim that he is in fact inconsistent. If he is also mediocre, his mediocrity would in theory be directly related to his consistency.
In a sidereal way, this is my point.
Green is, and always has been, used as if a 3rd option player. His USG numbers have rarely exceeded 24% for any extended time and for much of his career have been well below that.
I believe that Green's supposed 'inconsistency' is actually no different than the typical player with that sort of utilization. As I've illustrated, even Paul Pierce, when his USG dropped down to 23.8% in 2010, had essentially the same share of really low output games as Green has had (with a similar USG of about 23.5%) this season. In seasons where Pierce' USG was much higher, his share of low-output outlier games has been much smaller. So were his share of top-end outliers.
When Joe Johnson was at Phoenix, his USG was similarly just over 20% and he was similarly 'inconsistent'. Then, he went to ATL where his USG was typically much higher, 26-27%. His share of 'poor' games was much smaller then. Now, in Brooklyn, his USG has dropped back to the low 20s and he's already had far more games of under 10 points than Green has had.
The correlation seems pretty strong: Low USG players tend to have a much higher share of outliers, both low and high.
Green is used as a 3rd option player (a 'mediocre' player if that's what you prefer) and both his production and consistency are consistent with that role.
I don't understand why discussing this leads so many folks to get all emotionally charged. It's almost as if they have some sort of personal stake in their assertions that a player is 'bad' or 'good' or whatever. Any attempt to try to analyze what is actually going on gets labeled 'excuse making', or 'homerism' by the resident bullies on this blog. It gets old.
