I run the Packers' psycho D (the 1-5-5 prowl) a fair amount and the Packers in real life constantly shift the LBs and down linemen. In the game it can create some nano blitz situations (which is why I don't do it often) but if you see the prowl and you make sure to adjust protection, it can be easily beat. one secret. The play ya'll most likely talking about is the corner blitz, can't quite think of the name right now. But basically all the LBs and the D tackled are rushing, then the slot/nickel corner comes through c-gap. That's the most used play in that formation. If you see them doing that play, one guy will always be open. Depending on what side they're running the play on or what side you're running your play on it will either be your running back or your slot receiver. Easy yards, if not a TD. It's easy to tell if they're running play by how they shift or even how they initially approach the line of scrimmage.
EDIT - the play is called Under Smoke in the Packers' playbook.
