On a side note, from others who have tested, it seems the more PBK is upped, the more that the CPU seems to go downfield.
Ive been trying to do that with QBA. Im not sure if it works as well as having PBK up. But the higher the PBK the worse your pass rush is. And its already pretty bad.
I might actually try CPU QBA at like 70+ to see if they go downfield or not. But keep the PBK at 0. Im hoping with the generic playbooks that they CPU will play alot better while keeping the pass rush intact.
