i think for you to know that your game was really realistic stat-wise, you have to look at the FGA. everything will follow from that stat, number of FGs you'll miss, FG%, then from that the rebounds, the passes, turnovers the turnovers, etc.
you might get realistic scores, like 60's, 70's, 80's but if your FGA is around 50, it is still not a sim. the average team has 70-85 FGA/game. thats why the length per quarter is important for a real sim. from my experience, you'll get the right FGA from 9-min quarters. in 12-mins sometimes you'll reach 90 or even 100. thats not right.
BTW, is there a tweak out there for realistic 12-min games?
