Here's a defensive line discussion from the Alabama Football Coaches association convention. This talk covers what you as a coach can do to help build a successful defensive line with the kids you have...or develop.
What is a basic practice day for the defensive line and how the coaches coordinate the limited time they have to insure they get the most out of their valuable time.
Every day your defensive line should be tackling and doing stunts. Here a few stunts and drills are covered that will help your team develop.
Before the snap there are a things that have to be done every time such as down and distance or time and score. Your defensive line should also know what the offensive line is telling you by how he's lining up.
Alignment is based on several things, but your defensive linemen should never get caught in a reach block or give up a penalty!
Hand Placement is probably the most overlooked skill in High School D line play and you must try to work hand placement every day against live body Defense.
Getting off the block is the objective of the defensive lineman. It's ok to get blocked, it's NOT ok to stay blocked and that is where your defensive front guys knowing the different release types.
Effort and desire are critical to a successful pass rush, and knowing what the objective is as a rusher is important. Remember while a sack is great, there are other things that are just as helpful!
