I don't think my posts are personal, so I don't know why you are taking them as such. This is a discussion regarding Suggestions, which are made for the purpose of the betterment of the game. Let's just stick to that. By all means it's great to get ideas brought to the table where we, the users of the game, can kick the ideas around and the game developers will use our discussion as part of their consideration for game improvements.
I think Aggressiveness as it is treated here is considered more of an innate character trait rather than something that gets "trained". The skills that are trained have an "aggressive" component by nature, for example rebounding and defense (and most of the skills for that matter) require a player to be aggressive. But it's really hard to teach a person to be Aggressive in the BB sense. Perhaps part of the problem here is that the Aggressiveness here is related to body contact and fouling and not to precision. Until about the middle of last December, Derrick Rose was famous for not getting to the free throw line too often. He has always been "aggressive" in attacking the lane, but he would go for the best shot rather than try to draw the foul. Has he suddenly become more "aggressive" in the BB sense of the term these last couple of months? Well if he did, then he should also be committing more fouls, too. I'd just say he maybe improved his Driving skill (though resulting in more FTs rather than a higher FG% on layups).
Can Aggressiveness be scouted in a hormonally-charged 18-year-old? If this could really be assessed, maybe the likes of Eddie Curry, would have been scouted differently (who would have thought that skinny Tyson Chandler would prove to be by far more aggressive than Curry?). At 18, it's not easy to tell the difference between teen frustration/immaturity with long-term aggression issues (I wonder what Dennis Rodman and Ron Artest were like at 18?). That's my opinion.
And finally, do you really want this game to be as predictable and robotic as possible? Do you also want 3-weeks' notice before a player is scheduled for an injury, or to know when your best shooter is going to go cold in a game? Sometimes, upsets happen. Sometimes, young players full of potential turn out to be busts.
