These steps can be the difference between the running back being run down in the backfield or him getting to the hole and gaining yardage.
The counter scheme is a simple gap blocking play. In reality the offensive line only needs to change one block in order to keep it identical to the power concept.
Both plays are based around the front of the play, blocking down to create a wall while a player pulls to kick out the C gap player and another pulls and leads on the playside linebacker.
The playside tackle is responsible for the playside B gap. He will step down and block any defender that happens to be in the B gap. As he blocks down on this defender he will keep his outside arm free and his eyes on the backside linebacker.
