How to teach it

  • 1Man across the board with one deep free safety, so man defenders use inside leverage toward help.
  • 2A backer robs crossers underneath to help the man defenders on picks and crossers.
  • 3The free safety stays centered over the top of every route.

Common mistakes to fix

  • !Man defenders playing outside leverage and losing the post; fix by leveraging inside toward the free safety.
  • !The robber getting too deep and not helping underneath; fix by reading the QB and jumping crossers.
