Hold A or X depending on the console after you make the accuracy check to hold the snap off. If the guy tries to jump it he'll give you 5 free yards otherwise you get your kick off.

If they have came up with some sort of turbo blitz technique already then we are sadly doomed...though I'd try kicking as fast as possible.

To block one yourself simply comes down to timing the snap with one of the outside rushers or even the middle returning who is just over the LB. If you time it right you can either get to a point where you can jump and block it (the middle route) or make a diving block (the outside route). If your opponent is always snapping around the same time you should be able to get pretty close.
