I can confirm the issue is just the Cover 2 Zone play. Every other play, the CPU safeties react naturally. This could easily be fixed in a tuner, I'd think.
All in all, a fantastic patch that falls just short of being perfect in what it was trying to achieve. It's certainly frustrating that when the CPU runs a Cover 2 Zone, it pretty much ='s busted coverage for the CPU. I can live with this for a couple weeks if I knew that EA was aware of it and working on a fix.
