I already sent you the rosters I tweaked, and they more or less make the game perfect on All-Star...superstar seems to be impossible, even for a vet like me.
As for ratings, here's what I did:
FG: -15 all players
3pt: -5 PG,SG,SF and any 3pt shooting PF or C
FT: +5 all players (it pisses me off to shoot 40% with Vince Carter..*shrug*)
Quickness: leave it
Speed: -10 all players
Steals: -15 all players
Offensive Awareness: -5 all players
Defensive Awareness: +5 all players
Blocking: -20 C, PF, SF; -15 SG,PG
Primacy: -15 for PG; I've had guys like Derek Fisher, Charlie Ward, and so on just shoot three after three and end up with over 40 pts....
Hardiness: -10 all players (I like more injuries)
You should try to go through and make injury prone people injury prone...set Ilgauskus and VC and Hill and so on's hardiness at 50...
The game stats are pretty realistic...you may want to knock the fg down a bit more, but then it would probably be far too hard to make jump shots. Definately use USER shot control, as you can't make shit with the CPU setting...couldn't tell you why. *shrug* I shoot when I'm open with good shooters...
