As the receiver cuts inside, the defender grabs his outside arm jersey
Then, when he breaks to go outside, the defender pulls on the jersey to contain him
After he pulls him all the way back towards him and nearly down… The defender reasserts his grip, letting go of the jersey and re-grabbing higher up on the shoulder
At this point, he pulls a second time on him, pulling his jersey up over his shoulder pad
Next, as the player is still trying to get away, he wraps his left arm around the defender and basically has him around the neck and from behind
Once the player is 7 yards past the line of scrimmage he let’s go and at that point, Jake is about to get sacked
