In all fairness, there have been many changes to the sim over the years. When I first started, many elements in the game now didn't exist. There were no percentages for things like usage, rebounding, etc., or at the very least, if they were used by the sim, we didn't get to see them. Back then, there was a very specific two part formula for drafting players which would provide a winning team, and once you figured it out (or someone told you, which wasn't hard to get if you frequently the forums), then you were set.
There have been MANY changes over the years besides adding percentages. For example, at one point back in the day you could exploit the strike shortened season of 99-00 players, because the sim reduced their salalries to represent the number of games they had played, but pro-rated their games and minutes to an 82-game season. You could literally field an amazing team with players from that season on the cheap, but they would play like a team from other seasons. WIS worked to fix this, and I assume it hasn't been an issue since.
Back then, injuries depended upon the number of games a player had played, not minutes. The less games, the greater the chance for injury. Minutes only determined fatigue, which as is the case now, could impact the game and increase the chance for injuries.
Back then there were no defensive ratings, which was something people called for and (obviously) eventually got, no matter how flawed you may argue some of those ratings are.
There were also no percentages for permiter, paint, etc, and no percentages for what position someone played. There were no penalties for fielding a team of, say, all centers, other than the fact that your other numbers might not be balanced or proper for winning.
My point is there have been wholesale changes to the sim in my tenure at this site, and because I haven't played as much as I used to, I'm not sure I always field the best teams myself. In fact, I learn a lot by watching owners who do well now, such as several of you.
