http://www.basketball-reference.com/players/g/greenje02.htmlComparing Green's Boston production versus his Thunder/Sonics production....Green is virtually a more productive & more efficient player.
In both situations (for the most part), Jeff Green has had the fortune of playing alongside highly talented/gifted teammates. Only this past season has Jeff played with a somewhat "talent-lacking" group of teammates.
If one were to claim a young, developing Avery Bradley (compared to a hurt/injury recovering Rajon Rondo), was Jeff's best talented teammate....well then, your team is kinda playing behind the eight ball so to say.
Jeff's Celtic numbers are virtually up across the board (compared with his first team). Green's scoring rate is higher, TS%, eFG%, FT%, 3PT% --- all higher as a Celtic. The only dip (slight decline) has been rebounding. This may or may not improve if Jeff plays or does not play the PF spot.
I feel, realistic Jeff Green with more time playing alongside a healthier Rondo, more developed & confident Bradely & Sullinger & Olynyk....Green can produce a 17/5/2/1/1 on 44%/35%/80% efficiency (54% TS/49% eFG).
If Stevens and staff can somehow develop Jeff Green to accept a 1st or 2nd option offensive role for next year, it isn't out of the realm of possibility that Jeff increases the produce to 20-22/6-7/3-4/1/1 on a more likely lower shooting efficiency.
