I wouldnt worry about the ratings too much. They can easily be changed. Id be more worried about the things that are set in stone.
The menus...
EA really has a knack for making anoying counter intuitive menus. Honesty, i can't even imagine why the producers approved this rubbish.
The PDA is a horrible system. Having to click each section of the PDA to get a pointless message is very anoying. Couldnt they use the email system that Madden has? Only don't hide it in the menu's, make it the first thing we see on our nba live franchise desktop. Insignificant info like dropping down in the rankings should be colour coded and does not require an alert sound.
Anyone here played Championship Manager/Football Manager or even EA's Total Club Manager? This is the type of "email" menu we need. I dont wanna have to click on the PDA menu, then click on a box to get to the injury messages, then click on the actual message again to read it. And then back peddle two layers of menu's and repeat for the other categories...its freakin' anoying!
Rookies...
I really hope there isn't an abundance of 6'0 tall shooting guards again...Or SG/SF's that have 75 for quickness and 50 for speed
Coaches...
Their justification for coaches has me very skeptical about the quality of this feature.
"GS: Can you give us some general tips on managing your staff in dynasty mode?
DR: There are three strategies to use when you hire your coaching staff. Assistant coaches should be hired when a team is in a youth movement. It will help improve your team throughout the season. Scouts should be used when the team is going to be picking up a bunch of youth in the next draft. This will allow the user to scout more players, thus giving them a better picture of what kind of talent is out there and who can help the team. Trainers are useful, but one trainer should be able to cover what you need. If your team is old, but still good, you might want to pick up a second trainer so that you can keep your old players on the court instead of the injured reserve list."
These aren't strategies! Assistant coaches/Scouts/Trainers come standard! They are not hired as part of some lame strategy in real life...If its in the game, its in the game?

EA's approach to this new feature seems very very shallow.
I realise that i probably should have made some of these suggestions on the wishlist. Im not a regular poster here though, and besides, im sure the wishlist had many great suggestions that have obviously been overlooked. At least off the court anyway.
Im still optimistic about the gameplay, because that is what ultimately makes or breaks this game.

``They play the game the way it's supposed to be played,'' Iverson said. ``It's not about athletics. That's the game the way Karl Malone and John Stockton play it. It's good for kids to see how the game is supposed to be played.''
