Blocking is probably the hardest thing to teach and the hardest thing to learn in
football. The burden can be lessened if the coach can communicate
exactly what the
objective is and how to achieve it. As a coach there is a list of blocking elements that
you must be aware of and discipline your players to get it right (
See O-Line 101).   
When your players are running their drills make sure they always have a good, solid,
balanced 3-point stance. They must also know their footwork, handwork and
finishing the block in order to be effective. The overall objective at best, is a pancake
or to move the defender as far from the ball as possible and at least to occupy the
defender long enough for the ball to pass by them.

STANCE AND STARTS
STANCE
:  The offensive lineman’s stance is the basis of sound execution.  Without
a proper stance linemen are unable to execute their assignments or techniques
properly.  A proper 3-point stance consists of the following elements.
Base: We will be at shoulder width.  We would rather the stance be slightly more
narrow than wide. This allows for better lateral movement.
Feet: We want feet perpendicular to the LOS.  Feet should be flat on the    ground,
with a slight stagger, usually toe to instep.  Weight should be on the ball of the feet.  
We do not want to be on our toes or our heels.  
Power Producing Angles: A good description is to get a “Z” in the leg from the thigh
to the foot. This creates good power angles in the hips, knees and ankles.  
Arm and Hand: The down hand should be placed on the ground inside the knee
and under the eye.  Fingertips should be on the ground, not a fist.  Weight should
be distributed so that the hand can be picked up with a slight lean.  The off-hand
placed alongside the off leg in a cocked position.
Shoulders-Back-Tail: The shoulders must remain square to the LOS, with the back
parallel to the ground.  The tail must be in a position that it does not force the
lineman’s head into the ground.  The lineman should be able to see the DL and the
lower 1/2 of the LB. (

1-2-3 Progression”:
- Have players form 4 lines.  
- When the coach yells “
One” all players in the first line will properly set their
base         
-On “
Two” players lower themselves down so that their elbows are on their knees
and their head is straight ahead.
-On “
Three” players place one hand on the ground and the other in a cocked
position, level their back, and get their head up so they can see.  .        
Coaching points:       
Go slow.  Make sure that each athlete is in the correct position at every level.  
Athletes need to learn to get comfortable in a stance, so keeping them down for a
time is good.
- Have the players in the lines behind them coach the athlete that is performing the
drill.  This will help the coach and the players behind the drill.

Oklahoma - This is an excellent drill for your offensive linemen. Line up two
blockers and one running back against two defensive linemen and a linebacker.
Have your blockers create a running lane to the left, right or up the middle. The
coach stands behind the defense signaling which way to run the play.
