Playmaker,
I tried out your sliders in a Michigan Ohio State exhibition. They are pretty good...except I really think you need to reconsider the Human RB ability at 25.
Mike Hart was getting run down by DTs and DEs consistently. It's like the RBs are moving in mud.
I think if you bump Human RB ability up to 40 or 45...you'll get much better results with the RBs...it just seems to handicap the human running backs a bit too much.
But nice work on the sliders. I may have to try out some All American games again for fun.
