How to teach it

  • 1All four linemen step to their strong-side gap in unison on the snap, shifting the front one gap over.
  • 2Backers flow strong and fill the gaps the slant vacates.
  • 3The weak backer is the cutback insurance since the front is overloaded strong.

Common mistakes to fix

  • !Linemen slanting too flat and getting reached; fix by attacking the near shoulder of the next blocker.
  • !Cutback lane opening weak; fix by the Will reading and replacing the backside gap.
