I went 12-14 shots because his play will be better but his time on court will be limited. A chunker will always chunk but that what the offense needs so it should work. He likes to iso so he hold the ball —> slowly taking away from his teammates —> this will be his area of growth not his not his shooting or even his shot selection if the ball is moving. He is/was an all world player for a reason.
Depends on CP3 and Gordon's health, but I'm guessing around 15. Maybe a bit fewer. Gerald Green averaged 16 FGA/36 min last year. I could see Melo being around that number.
