There's been zero indication in Green's career that he's going to be more productive on a per minute basis if he plays more minutes.
As mentioned, his per36 production has been remarkably similar over his career, and remarkably mediocre too. A well paid 6th man has to come on and do damage in his minutes, like Crawford is doing for the Clippers, or JET did for many of his years in Dallas.
DA could have gotten any bargain basement scrub to score 9 points on 43% shooting in 22 minutes, grab a rebound every 7.5 minutes, get an assist every other game, and play mediocre defense.
Green has been a total disaster as a 6th man for the first quarter of the season. At $4m a year, it's not as big a deal as at $9m a year. What concerns me the most is that he isn't willing to play hard for any stretch of time whatsoever. Jeff Green has a Tourette's Syndrome motor. Once in a while, he'll burst out with something loud and memorable, and the rest of the time he just floats through the game.
I can't wait for January 15th, and hope there's an NBA GM who wants to pay $9m a year the next 3 1/2 years for something he can get for three or four million.
