😱 On May 10 John Teerlinck, one of the greatest D-Line coaches of all time, passed away. Coach Teerlinck coached greats like Robert Mathis, Chris Doleman, Kevin Greene, Dwight Freeney and John Randle.

In honor of all he has done I broke down his famous 3 on 1 drill below..
Why do the 3 on 1 drill?

One of the key fundamentals of Coach Teerlincks system is to get off vertically vs the run and the pass. With this mentality, D-Linemen need to understand how they should fit and react in both run and the pass situations with this aggressive technique.
Tight 5 set up

You need 3 blockers to simulate the tight end, tackle and backside guard
Tight 5 Reads

Double team: The 5-tech wants to get their hat in the crack and split the double team

High hat: The get off should put the lineman in perfect position to pass rush

Down block w/ pull: When the 5-tech reads down block and sees the pulling guard he needs spill
Loose 5 set up

You need 3 blockers to simulate the backside guard, tackle and fullback
Loose 5 reads

Reach: Get upfield and penetrate vertically

High hat: The Loose 5 needs to be aggressive and win off the edge if the tackle shows high hat

Down block w/ pull: When the D-Lineman reads down block and sees the pulling guard he needs to spill
3 tech set up

You need 3 blockers to simulate the center, guard and tackle
3 tech reads

Scoop: Get hat in the crack and sprint down the line to make the play

High Hat: Pass rush without taking any pauses. Remember the 3-tech's steps should be the same on run and pass.

Trap: When the 3-tech reads down block and sees the pulling center he needs spill
Cocked nose set up

You need 3 blockers to simulate the center, guard and tackle
Cocked nose reads

Scoop: Get hat in the crack and sprint down the line to make the play.

High Hat: Everything happens faster in the interior so the nose needs to work his move immediately with high hat

Reach: Vertically penetration creates! Vs the reach get vertical!
If you liked this breakdown, I send out a free D-line case study email ( http://bit.ly/dline-weekly ) every Monday that goes in-depth on different techniques D-linemen use in live situations just like this one. And again thank you Coach Teerlinck for all you have done for the game!
