westfieldDefensive line play is paramount for overall defensive success.  Although there are numerous different ways to teach fundamentals, I always revert back to keeping it as simple as possible.  Extraordinary play occurs when great fundamentals are combined with unbelievable effort.  The guidelines I use to cover all bases are remembered by the initials “S.A.K.A.”.   In order to be a great player, he must have a great Stance.  For defensive success to occur, the front must be properly Aligned.  A player must know what his Key is and how to attack it.  Finally, the defensive lineman, must know his Assignment.  These 4 components are the backbone to success and as previously stated, when combined with unbelievable effort, result in success up front. 

When referring to block destruction there are multiple issues/questions that can be asked and emphasized.  When people ask me the why’s/how’s of this topic I try to refer to a sequence that can easily be evaluated with players.

Ball get off-  How well are the players reacting to the snap?  When they get off the ball are they taking a short step to enable them to change direction or is the first step too long caused an elongated base?  How far are the players off the ball? Personally I’m a crowd the LOS guy because we base out of an attacking front.  What is stance like prior to snap? It’s tough to ask someone to attack with a flat back. 

Attack points-  Where are you telling players to attack?  Most schemes work on half the man but the biggest mistake made is when players are practicing on bags/sleds they attack the middle.  If a player is attacking half the man, essentially the inside hand should target the breast plate of his opponent and the outside hand on the shoulder/bicep area. 

Emphasis after contact-  Every defensive lineman “cries” about being held…my response to that is did you “shock and extend”?  Most of the times the answer is no…SEPARATION EQUALS SUCCESS…no separation/no excuses…

Block recognition- What is it? Down/Reach/Base?   Players should know how to attack each one and their progression of getting to the ball.  If it’s a down, player needs to attack and drive.  I tell my players this is where you basically turn into an “offensive lineman”…if it’s a base, shock/extend and force ol back in the hole…if it’s a reach, attack through the outside shoulder, lockout, separate, long arm/short arm, rip release and get to your pursuit landmark- NOT the ball.
