I can't exactly call it that way, but looking at some other posts, I can say Green is well above average in terms of potential for his position, which is primarily the SF spot.
He can play PF when he is demanded to do so, but won't blossom in that position. He is young, he is athletic(you don't have to be blocking shots to be called that way), he is quick enough to defend many of other forwards, and from what I saw in his OKC days, he doesn't think he needs to continuously shoot the ball for success.
I have monitored him beginning with his rookie season and at first, couldn't really understand why he was the center piece Seattle was getting back for Ray. He looked lost. Then again, even Durant looked miles away from being efficient, often struggling with his shooting. Green looked even worse.
But as years went by, I changed my opinion about him as his on-court awareness improved, and he began to utilize in his role as an NBA player.
Ibaka > Green isn't the main reason OKC traded him. It's because they got someone to start in the center spot (Perk) with trade. They may be forced to give up on Harden in the near future, as well, while trying to lock up other spots in the team.
As I have already stated in the other thread, I'm not that much into bringing Josh to this team. Hats off to him for his excellent season, but it's fair to say this is the only season he really gave his head to the basketball, primarily because he became his team's first option, with JJ struggling.
I think we should add Jeff if he's willing to come and we have the financial flexibility to do so.
