I don't know, man. I had the Knicks the other day playing the Bulls at Chicago and the Bulls had 18 points in the paint in the first quarter. I had to change my defensive settings to "Protect the Paint" or whatever it's called where you're players sag off and help in the paint more.
Keep in mind, each game will be different. The variation you get in this game is pretty cool once the settings and roster are both set correctly.
