I don't follow the the bulls so I won't suggest any roster lineups.
However, I'll give you some of the changes I made to make the game a bit easier to play.
First of all, after the 15th game, you should have caught on on how to slow down the fastbreaks. It will still happen, but they won't be able to build a 20 point lead on fast breaks.
Do not bother posting up. It will only get your ball slapped out of you.
Grab Yao Ming. I know some people don't care for him. But EA seems to have made him really good. He's big, hardly gets blocked and can shoot from almost anywhere.
Now as far as settings go. I would turn fouls all the way up. That way the computer gets called for reaching in more often. I like that because they tend to cheat a lot by stealing the ball on every other possession. I was able to cut down on turnovers that way. Not to mention put a lot of their players in foul trouble. Since its hard as heck to steal in this game, you probably won't have as much of a problem getting called for def. fouls.
Also, in the gameplay settings. Set your cpu assist OFF. That way the computer has a harder time coming back when they are down. They will still make runs but they actually miss every so often.
Next, switch the game to Arcade instead of Simulation and turn on all the rules. I've noticed that this makes the game just a little bit more realistic. Not much, just a little bit.
Other than that, watch your game play. Its VERY easy to turn the ball over in this game...like all other NBA lives. Don't pass the ball in traffic, don't bother setting up alleyoops because 75% of the time you'll miss.
Defensively, you can stop players scoring in the low post by switching to the guy guarding him and pressing the "take charge" button. 70% of the time, you'll draw the offensive foul even if you're inside the circle under the basket.
By the way, dunkers are almost unstoppable. They will draw fouls and score. Whereas guys that lay it up will have their layups interupted.
Right now my record stands at 13-6, 8 minute on superstar mode and with those setting I told you about. My FT% is horrendous because its hard to shoot FT in superstar mode. My FG% is actually way better (around 60-70%). Talk about realisms huh?
