I didn't expect Green to become a super star, I expected him to be able to average 20 a game.
This, and I still think he can be an 18-20 PPG guy.
The thing with Green that makes him such a question mark is that everything is mental. Green is shooting reasonably efficiently from the field and a nice percentage from three. If he played with more aggression offensively and took 3-4 more attempts per game, then he would be right up there aroud the 20 PPG range.
He is absolutely CAPABLE of putting up those type of numbers, he just lacks the aggressional mentally. It still feels like he's not used to being the #1 guy, he still feels like he's playing behind Durant/ Pierce and he needs to let his shots come to him rather than going out and getting them.
That said, we still don't know how his game will be affected once Rondo returns. Will Rondo hold on to the ball too much, in turn hurting Green's touches? Will Rondo's elite ability as a set-up man give Green more (and better) scoring opportunities?
We'll find out soon enough!
Anyway I still think defense is where Green is most underrated. Statistically the last time I checked he was one of the best defensive small forwards in the NBA. Everybody talks about his offense because everybody things of him as a scorer, but his defense (especially against elite opposing swingment) is arguably the most valuable thing he brings. He has the defensive skill set to shut guys like Lebron, Durant and Carmello down - something he has proven in the past, and something that very few players in this league can do. Add that to a relatively efficient ~17 PPG and he's quite a valuable player.
