Here's how you turbo blitz in NCAA 11. This makes it so that you can manually blitz or manually drop into coverage without having to have that split second reaction to the hike.

Hold the coverage audible button.
The right analog left or right
Then the left analog in the direction you want to go.

just a FYI, when u do this, it will shift the DBs in blue zones to the side u choose on the right analong

this is tight im liking it but it is kind of hard to hold on the controller.

you dont have to hold triangle. just hit it so the coverage stuff comes up
