This has been a game changer for me. I started with a team that doesn't have a very good run defense. I've been trying to simulate that with no luck but after putting CPU fumbles to 60 the CPU finally has a strong running game against me.
Also tested CPU QB accuracy being attached to playing calling. I can confirm that's 100% true.
I had the CPU pass accuracy around 20 and the CPU was running way too much. Had to bump it up to 40 to get a reasonable mix.
This thread nailed down some things with sliders I don't think anyone knows about.
It just shouldn't be this way...and I can't see any scenario where EA addresses this. CPU accuracy should have no effect on playcalling. There's no way they did this on purpose.
