Ringo, you were right. I think I underestimated the VIP feature. After about 180 games, the CPU knew pretty well that I like to establish the run, and almost always run on first down. I have started passing more, and that has opened up a little space for the ground game. Thanks Ringo!!
It is still a struggle, but instead of avergage pickups of 0-3 yards, I am getting a more realistic 3-5 yards per carry. That is enough to make the running game a legitimate weapon.
I still don't see too many carries more than 12 yards...but if I had to choose, I would rather see too few than too many.
Thanks for all who chimed in.
