Player freeze button

[thejimmy]

On PS3, how do you "freeze" a player to prevent him from crossing the LOS prior to the snap when you are going to nano/turbo blitz? On 360, the video said to push Y which would correspond to the triangle button on PS3, but triangle also brings up coverage audibles so I'm wondering if it is a different button. Anyone know?

Due to the number of replies, I did some experimenting...and found out nothing. I used all of the buttons and nothing would freeze the player. Annoying. So my next question is...how do you switch the formation from side to side before you call the play, not while you are on the field?
