How to teach it

  • 1Both ends slant inside to opposite B-gaps behind the tackles to disrupt inside zone and double teams.
  • 2Backers scrape to set the edges the crossing ends leave open.
  • 3The ends aim for the far B-gap, attacking underneath the down blocks.

Common mistakes to fix

  • !Both ends crossing into the same lane and clogging; fix by assigning clear opposite B-gap paths.
  • !Edges left uncovered; fix by timing Sam/Will scrapes to the cross.
