How to teach it

  • 1All four linemen step to their weak-side gap together on the snap to jump backside runs.
  • 2Backers flow over the top to fill behind the slant.
  • 3The strong backer is the cutback insurance.

Common mistakes to fix

  • !Front slanting late and getting washed; fix by stepping on the snap in unison.
  • !Cutback opening strong; fix by the Sam reading and replacing the backside gap.
