I don't get this "more aggressive" talk. I thought part of the problem was that he was too aggressive looking for his own shot and had zero ability to create for others. I don't want Green to be too aggressive with the starters anyway since he's an inferior scorer and for some puzzling reason, it's tough for Paul and Ray to find shots to begin with.
He didn't have a single skill that allowed him to fit in with the starters besides running the break and there's only so much you can do that against good teams.
Is he a good shooter? No. Erratic.
Good Passer? No.
Rebounder? No.
Defender? No.
Moving off the ball? No, though showed spurts of it in one game against Miami.
He doesn't need to fix a lack of aggression, he needs to improve his skills to become a solid contributer and not one whose deficiencies shooting the ball, rebounding, defending and passing make him a liability on the floor.
I disagree, because like it or not, he's going to see time with the starters playing Posey-like small ball.
If he can be aggressive and look for his own shot, he can be dominant in a similar, but different way that Shaq was. Shaq benefited so much from playing with the 4 starters because the opposition looked at him as an afterthought. Consequently, he looked better than he actually was at 39 (and better than he did at 37).
Green can do the same thing. Maybe he will never be an All Star, but he can exploit sleeping defenses.
Did you watch Shaq at 37? I bet this playing better you saw was from you watching a rusty Shaq in the playoffs after being injured and out for months (after the thumb incident). Shaq was playing very good before he got injured with the Cavs and put up better numbers on the Suns the season before. I know you all would like to think Shaq had become terrible (before the Big Three) but STATS say otherwise (and your eyes would too if you followed him)!
Now, onto JG... I don't think he is trying to be P.P. (some suggest) but he is pulling good things from a better player to emulate! EVERY player (including MJ) took good things from players before him to become a better player... that is a good thing! Also, you say JG is not "good" (not great for sure, but don't go overboard) at those things, funny how the professionals (including teammates) think he is... they also said he wasn't aggressive enough, he didn't just come up with that out of the blue, the coaches and players told him he needed/needs to be!
JG wasn't terrible but he gets a lot of grief from a lot of people. People (especially young ones), need time to be comfortable with being assertive when you have 3 All-Star caliber vets who you play with and don't want to be seen as trying to outshine them. Now he has realized he is suppose to do more (Big Three wants him to), he is saying he is going to go out and try to do it... that's all I can ask of him at this point!
