The AI forces about 6 to 10 TO's against me per game with the steal slider like it is, I would prefer they even got more. Soce plays with more minutes so that may be 1 factor the other is dribble penetration. You'll definitely get realistic scores, in fact you might want to bump up the minutes to 14 or 15 if you like higher scoring games. With 13 minute sliders I get scores usually in the 60's, occassionaly in the 50's, sometimes in the 70's and will get into the 80's once in a while.
Go with whatever sliders you like. Soce and I tested sliders for hours while chatting on Xbox live. For the most part our sliders are pretty much the same with just a few areas where we saw differently because of our play style. He does more dribble penetration where I use alot more passing to get to the hole.
