How audible in case of violation
After you've chosen your offense and the opposing team chooses their defense, the game will jump into action on the pitch, where you have a number of pre-snap options available to you. Checking your play can be done with R2, which is a good thing to do early on to see how well it matches up with defense. For run play, it will appear in green when you have lanes open to try, although this is not a guarantee.
If you see that you don't have good games against the defense, you can completely change the game. This is done by listening to the playback, which you do by pressing X. Once you press X, a new one. window will appear with a list of predefined readings for that specific offensive book. These can be changed before the game if you want other games to switch as well.
What you can do here is press any of the buttons corresponding to the reading you want to switch here and it will do that automatically. Just make sure that you don't want too long at the point where the game timer is about to run out, as you have to wait until the new game is set before you can smack the ball.
In addition to switching entirely to other games, you can also choose to reverse the game in this menu if it looks like the reverse would lead to better matches. If you don't like any of your edits, you can also go back to the original reading here.
