As far as Im concerned, sliders have nothing to do with simmed stats. At least not prepatch. I changed my slider in very drastic way several times and the simmed stats did not seem to change.
Only way to reduce the rushing yards is through coaching philosophy sliders I think, but that would mean way more passing yards then, because its not the rushing attempts that seem to be wrong, but obviously the average (6 or 7+ yards for the best?!) is just out of the world.
I wonder why the average was chaanged anyway, I thought I read that Looman did not want to chagne them because he predicted just this developement in his thread about the sim stats. And if I remember correctly, most people wrote that it was better to have some good backups crawling around 3.5 avg than to have what we seem to have now.
Maybe I should reread the thread.
