A: When unexpected players rush the passer, we call it a blitz. A cornerback could blitz. Or a safety. Or a linebacker.
A blitz could come from anywhere, at any time. That's why you always have to be ready to block. If you don't pick up the blitz, that is, block the unexpected pass rusher, our quarterback will be tackled and possibly injured. We don't want that to happen.
Like I said, any player could blitz at any time. They don't have to announce themselves. They don't have to raise their hands before the play. They don't have to shout "blitz!"
They don't have to count any Mississippi's.
This is the NFL. No one has to count Mississippi's in the NFL.
I don't think this "Let Your Daughter Play Fullback" promotion will be as successful as management hopes.
