Alignment • Cornerbacks
– 7 yards deep off outside shoulder of #1– 2 x 6 if #1 is a TE
• Safeties– 1 x 8 off #2 (TE) or imaginary #2– 8 yards deep off inside shoulder of #2 if
removed
Stance• Toe-to-heel stagger with outside
foot forward. 70% of weight on outside foot
• Eyes on Key

Pass key: Pass key: Run key:
• Safeties: #2 and Uncovered lineman– #2 run block with run block by U.L. is run
key
– #2 release with pass block by U.L. is pass key
– If no #2, key is just the uncovered lineman
AssignmentAssignment
• Key QB for 3-step drop• “Low shoulder” your side, plant and drive forward when hands separate, bringing eyes to #1• “High shoulder” your side, crossover, play Fade, and become the intended receiver
• QB takes deeper than 3-step drop, bring eyes to #1 and play his pattern
CB’s:3-Step slideback regardless of run/pass key
• QB hands off: pick up backfield flow and bring eyes to #1 and play him for play-action. If blocking, start up on run support
AssignmentAssignment
• If pass key, 3-step slideback and key release of #2
• Vertical release by #2, you have him man after 8 yards• Inside/Outside release by #2, bring eyes to QB
• QB shoulders on your side, rob #1• QB shoulders away from you, key his release
• If no #2, key QB to possibly rob #1
Safeties: Flat-foot read
• If run key, bounce as you pick up backfield flow
• Flow TO you, work downhill (Force player)
• Flow AWAY from you, work downhill (Alley
player)
Run SupportRun Support• With a run-read, DBs will see one of three things:
• Inside run• Outside run--to you• Outside run--away from you
Elements of Run SupportElements of Run Support
• Force Player
• Secondary Force Player
• Alley Player
• Cutback Player
Run Support Calls
• “Sky” means a Safety is the Force player
• “Cloud” means a Cornerback is the Force player
• “Bronco” means a Backer is the Force player

Vs. Bootleg Pass
SS gets pass-read, inside release by #2, and robs #1.
FS gets pass read, has no #2 release, and looks to rob #1. If #1 vertical, look for crosser.
Will starts to flow downhill, sees boot his side, and picks up first back in flats.
Sam starts downhill, sees boot away, and looks to get under crosser.
Mike starts downhill, sees boot, and becomes second contain (behind DE).

Sam/Mike are playing run. Lock-up with closes backs.
SS gets run-read, and fits for Force. Takes any outside release by #2.
Cover 4 Formation Adjustments
• We will make the following
adjustments if we are playing
strictly Cover 4

Vs. a wide #2, LB that side will split difference between him and EMLOS. Since #2 is wide, safety that side can't afford to flat-foot read (3-step slide-back). FS should check to "Bronco" force, since he's in a pedal.

We will "cowboy" vs. single-width Twins. This allows us to stay in Sky support to both sides, and lets safeties make the reads they are used to
