What beats what?

Question
What plays would you use to beat the Cover 2 blitz, a Cover 3 Blitz, and a all out 4-3 blitz?

Answer
Not that I am a coach or anything, but the way to beat a blitz is to go behind or around the blitz.  Quick slants and screens get the ball behind the blitzers (as a pitch out or swing pass gets outside the blitzers) and most importantly get's the ball out of the QB's hands quickly.

What you don't want is the QB sitting there waiting on a long fade, post or some long waggle.
