I think it has more w/ us knowing when they're running and dialing up a good run D.
Believe it or not but by giving running teams a running PB, ie. Panthers, Vikings, Titans or even a generic book like Run N Gun, the cpu seems to run for 100+ every game vs me.
If they break a big one then they have 150+
Really the Run N Gun works well for running teams w/ a mobile qb, they surprise you and run on 3rd and longs and keep you guessing on the 1st and 2 downs.
Panthers have a nice gameplan.
Patriots have a nice passing gameplan, they use the WHOLE field lol
