you can choose random play already, but im sure you want it to be more in depth and i wouldn't mind it too much either.
what i would really want is an adjustment that tells the computer how long before it snaps the ball or something like that, so it is not completely necessary to get a second controller or even use a second controller because it is annoying to have two constantly by you to control. i hate practicing defense and then snapping and realizing that the qb will never throw the ball and will just stand in the same place till i sack him or pick up the other controller
