Dive Key

Offense

also: dive read · No. 1 key · mesh key · first read

The unblocked interior defender in an option play whose post-snap reaction tells the quarterback whether to hand off to the dive back or pull the ball.

The dive key (often designated as No. 1 in option counting systems) is the first unblocked defender the quarterback reads in an option scheme.

After the snap, the quarterback rides the running back through the mesh point while watching the dive key:

Give
If the dive key stays wide, widens his stance, or sits in his gap to defend the quarterback, the quarterback gives the ball to the dive back attacking the interior line.
Pull or Keep
If the dive key crashes down hard inside or turns his shoulders to tackle the dive back, the quarterback pulls the ball and works to the next phase of the play.

In traditional Veer and Zone Read schemes, the dive key is usually the defensive end on the edge of the front. In Midline schemes, the dive key moves inside to an interior defensive tackle (a 1-technique or 3-technique).

A note on how the term is used

In triple option systems, the dive key is the first read in the sequence, followed immediately by the pitch key on the perimeter.
