A lone defender squares off against a lone blocker.
Bags or cones can be set up on either side of the players, approximately 5 yards apart. This willlimit the lateral distance that each player can move.
The coach standing behind the defender assigns the direction to the blocker telling him which way to take the defender. The defender needs to read the will of the blocker and fight through the pressure to the hole.
The object of the drill is as simple as the game of football itself--beat your man!
