where they show the shell before the snap
and rotate one safety into the middle of the field
the reason is to protect where the chunk plays happen

The concept also is to double cover the routes and
not cover a zone where no one is.

here the left flat is not covered because the back
is blocking and releases late, and in that case
the LLB (Jack) can break of the TE option route
and rally and make the tackle

the outside corners are doubling the outside routes.
How? the sideline. The sideline doubles the WR
because it helps the CBs. The Qb has to throw over
the CB because the CB reroutes the WR to the outside

the LS rotates into the hope and waits for the in cutting route
where the Star (always on the opposite side of the Jack
trails and if he's good can even undercut the route.

The MLB can take the inside cutting route if the TE goes in
the Jack takes it if it is outside the the TE is bracketed

The defenders are expected to match their zone coverage
to the patterns.

They play off because they don't want to spend time covering
someone who may be running an option route or crossing
they wait until the pattern "declares" then when they cut to
the route they break to the ball

No good Qb is going to tip where he is going with the ball
so there is no need to cover early anyway. Yes, it does
give up some 3-step completions, but it takes away
the biggest danger in football, the seems and middle
chunk plays.
