I'm wondering the same thing right now. I went ahead and used the sliders that you pointed me to, but I went a little deeper and started tweaking the "priority" and "style" sliders.
Dont know if its doing anything though, lol.
The way I'm going about it is if a team has a weak QB, I'll drop his priority slider down to 50.
I'm doing this for all positions, along with the "run vs pass" sliders etc.
