and I think the most important thing to figure out in the SIM is how much of everything you need. You need certain baseline values for your team in terms of scoring, DReb%, ast%, efg%, minutes (really most anything) and you need to be careful to not pay for stuff you won't use. Your team needs about 19600 minutes for a season, so don't draft 21000 minutes - it means you're paying for extra minutes that you can't use. And in an open league, you can count on getting at least 600 minutes or so from your rookies, so you really don't need to go over 19000. You can go even less than that, but that takes constant attention in terms of switching out players to avoid fatigue issues. Don't draft 13000 points, because your team won't get anywhere near that, and you're sacrificing somewhere else (probably in terms of efficiency) for all those points.
It takes some figuring out to see how much of everything you need on your team, and therefore how much you need to pay for different commodities. Just look at the successful teams in your league and see how their teams are put together, experiment a little, and you'll catch on eventually.
