How to teach it

  • 1'Sky' = safety rolls down to the flat; the free safety and both corners take the three deep thirds.
  • 2The strong safety supports the run in the strong alley since he's down low.
  • 3Backers carry verticals then settle in hook/curl.

Common mistakes to fix

  • !Strong safety rolls down too slow and the flat is open; fix by teaching an aggressive downhill trigger.
  • !Corners squeeze inside and give up the sideline third; fix by teaching them to stay over the top of the No. 1.
