In Cover 2, corners relate to the #1 receiver and keying the end man on the line of scrimmage for a pass/run key. On run action TO him, the corner should maintain (outside) leverage on #1 and squeeze the running lane to shut off the perimeter from the ball carrier. On run action away from him, he should sink and expand in relation to #1 (again, maintaining leverage as run force).On pass read from the EMOL, the corner should immediately scan the stem of the #2 receiver, to determine how he responds to the route.
#2 Inside - #1 Vertical
#2 Outside - #1 Vertical Inside
#2 Flat - #1 Vertical Outside
#2 Vertical - #1 Shallow
Smash , open hips play the '7' (corner) route. As mentioned above, this is a situation where if the corner bites on the shallow hitch, he opens the width to the deep sideline to a point where the half field safety is helpless to defend.
#2 Vertical - #1 Vertical
all go" (no other threat to the flat) and should collision #1 and carry his route vertically. With nothing left to defend, he can help the safety out (hopefully collisioning #1 enough to prevent both receivers getting vertically at the same level).
