I just make a 'gameplan' before hand. Like against the lions I stuck to cover 3 in nickel to avoid the big plays... But they ran calvin in the slot running crossing routes so I switched to 4-3 so he'd get smacked by a linebacker hoping for a drop. I manually move my safeties closer to the line, shift LB's/dline presnap but that's about it.
On offense I've been using two tight end sets with colt lyerla and Julius Thomas so I have a huge speed advantage for tebow
he can actually make throws if I keep my receievers within 10yds from scrimmage haha.
I'll try your modifications and raise CPU pass acc back to 50.
