Seems today's game with emphasis on Offensive Linemen "Sitting Down" instead of "Firing Out" would allow for a Linebacker to disengage after a "Shiver" Technique without regard to momentum "follow through". This means rarely will the "Shiver" Technique stop a blocker totally in his tracks. The "Shiver" Technique usually will allow just enough separation for the attacker to free himself to pass a block. If you watch the video closely, you will see the window allows Offensive Linemen to be successful even when a good "Shiver" Technique is applied..... WATCH: As the Linebacker shoots his hands forward in the "Press" position, he creates separation (GREAT), but on his release to pursue to ball, his elbows also shoot backwards creative a reverse momentum of his upper body. All this happens as he attempts to move forward-laterally to the ball. IN THIS INSTANT, a Lineman who is following through his initial approach still has the opportunity to re-engage the Linebackers body, as the Linebacker has just left his body open by returning both elbows backwards. This video is an amazing example of the Quickness, Strength, and pure Violence with which Linebacker should apply a "Shiver" Technique. I am looking for the next video that shows the uses of the "Trail Hand" that assures a complete passing of an offensive blocker.
