They're holding teams that low because they are running half court and have tremendous rebounding. Fewer possessions = fewer points. A better stat to look at is def fg%. #1, 2 & 3 in the league do reside in the Pacific. Look at Cubicle's defensive ratings. Then look at Sometimes' defensive ratings. Then look at mine. There's no way I should be even close to those two with my three 60s in the starting line up (one of the 60s splits time with a 41, too), but I am. But yes, defense has an effect - it's just inconsistent with other aspects of the sim. You have to look at it in a relative manner. emarvel & felonius both have good defensive teams and are leading the league in def fg% because of it. I have an above average defensive team and am third. While we do have a couple of poor teams, we have each other. And my two leading scorers are shooting 60%+ from the field, so that's not exactly something easy to defend.
That was never my point about defense, though. My point about defense was the defensive positioning feature... it actually hurts good defensive teams, because good offensive teams make it impossible to get the right positioning to play against it. In theory, you should play a -1 or more versus almost everyone, and I used to do that, but it bites you in the *** every so often. What ends up happening is that the dice roll in a different direction and cause you to have tremendous foul trouble. And when you do nothing, you get eaten alive because you're playing midrange constantly. And even then you foul a lot. That's the reason I started building my teams the way I do, and why I don't particularly care for midrange dominant players. I want a heavy paint scorer, a bomber, or a specialist (rebounding, assists, etc). Low fouls, average to good defense (instead of elite), and worry more about offense - and you'll be way ahead of the elite defensive teams. Watch what happens throughout the season in the pacific. The cubicle team doesn't have enough offense to remain at the pace it is on. What offense it does have is all perimeter. Don't run a +3 on it, you'll get eaten alive like I did. Try a +1. Enough to effect what little offense it has, but not so much you'll get killed when the dice roll the wrong way (and not so much that you'll get killed on the boards... you'll still probably get beat, though. It is truly one of the best rebounding teams I've seen that didn't decide to start Rodman at the 3, 4, & 5).
Cheers! Off to the beach
