Green is like the modern day Marion who doesn't know when to keep his mouth shut.
Can do everything reasonably well, nothing spectacularly, overrated defensively (still good, just overrated), gives the illusion that he can create on offense. Can shoot, can pass, can dribble, but would struggle if the opposition actually decides to hone in on him. Benefits immensely from PGs who can shoot at an all time great level.
Marion received the max under an environment where max contracts were given out much more loosely, and even then it backfired badly. So no, Green does not deserve the max.
