Backside Tackle

How to teach it

  • 1Teach the QB to read the flat defender: if he widens, hit the curl; if he sits, hit the flat.
  • 2Curl receiver settles in the open grass, not on the run.
  • 3Full protection means everyone keeps their man off the QB — no early releases.

Common mistakes to fix

  • !QB stares down the curl — fix by drilling the eyes on the flat defender first.
  • !Flat route runs too deep — fix by setting a landmark at 3-4 yards for the flat.
