Here are some examples of the three plays we will be looking at to demonstrate the Zone-Read:
1. Succesful handoff to the RB
2. Successfull QB keeper
3. Proper defensive containment on both the RB and the QB
On a zone read, the offensive line immediately crashes down to the play side (the side the RB runs toward). They use a zone blocking scheme, which in its simplest terms means they just block whoever is in their way, instead of blocking a specific defender. Occasionally, a lineman may pull to the backside (quarterback side) to give the QB a blocker. This immediate crash to the play side is designed to draw the defense to stop the run on this side of the line. Biting too hard toward that side is what lets Colin Kaepernick run for 45 yards in this play.
Notice the immediate hard step each of the linemen take to their left. Also notice #50 of the defense is left completely unguarded. His actions will be read by the QB.
The RB starts the play to the side of the QB and ½ to 1 yard back. When the ball is snapped, he runs into the ball just in front of the QB ready to receive the handoff. Unlike most running plays, he does not immediately grab the ball; he keeps his arms open, ready to have the ball taken away. Also unlike most plays, the RB is responsible for the handoff, since the QB’s focus is on the read. He ignores the free defender and focuses on finding a hole in the line to run through. If the ball is kept by the QB he then becomes another blocker. The RB always runs to the opposite side of the line as when he started.
This play is always run from a shotgun or pistol formation. Pre snap, the QB must identify which defender is the end man on the line of scrimmage (EMOL); this defender is the one who will be unblocked. This player is usually a DE or OLB. When the ball is snapped, the QB holds the ball in front of him for the RB and keeps his eyes focused on the EMOL. The EMOL has a choice:
1. He will either dive in behind the line and attempt to tackle the RB while still in the backfield. If this happens the QB will pull the ball away from the RB and run around the EMOL
Here is the full play again. Russell Wilson takes the snap, sees the defender move to the running back, pulls the ball and runs for a 15 yard gain.
This is what the QB is seeing at the moment as he makes his read – #50 is the man being read in this play.
Notice all the defenders have their momentum moving to the left. This allows the QB to pull the ball and run around him, as he cannot recover in time. Also, notice how much #50 has to turn his hips to follow the play.
2. The EMOL can also stay on the edge and attempt to contain/tackle the QB; if this happens the QB will let the RB take the ball and fake a run to the edge. This is the default option, and if the QB is ever in doubt, it should be handed off.
Here is the full play. This time Russel Wilson receives the snap, and sees the defender drive up the field past the line of scrimmage, he hands the ball off and Marshawn Lynch runs for a 7 yard gain.
Here is a series of images showing the EMOL and his path to follow the play. Notice he goes in hard and ends up level with the RB. This means he has to travel the same distance as the RB, but from a standstill while the RB has a running start.
This is what the QB is seeing as he makes his read.
Notice the EMOL has his weight moving forward, and is several yards away from the offensive line. He does end up making the tackle, but at 5 yards past the line of scrimmage.
A successful defensive counter to the zone read requires several elements. Generally, the defense is more successful at stopping the running back, which means it is typically better for the DE to commit to the QB. This requires a safety to make the tackle, which will usually happen 5-7 yards out, or for a linebacker to shed his block to make the play. When the DE commits to the RB, it is typically when the huge runs get broken, as this can put the QB 1-on-1 with either a corner or a safety.
In this play, Colin Kaepernick takes the snap, sees the defender move toward the running back, pulls the ball and runs toward the sideline. He is chased by the OLB and is run into a cornerback, forcing him to slide for a 2 yard loss.
Both of these attempts by Kaepernick are stuffed because #50 moves to the RB, but stays neutral enough to chase Kaepernick into a cornerback who has shed his block.
This image shows the moment that the QB makes his read.
Notice how far #50(the player on the far left) is leaned towards the line of scrimmage. The QB made the correct read and kept the ball, however, the athletic plays by other members of the defense led to a loss of yards.
Here is an example of an incorrect read. Drew Stanton takes the snap, sees the defender take a step toward the running back and makes the incorrect assumption he will continue towards the RB when actually, the defender recognizes the play and gathers himself to make the play for a 3 yard loss.
The EMOL’s first 2 steps lead the QB to pull the ball and keep it, however, the EMOL had not committed himself to the RB and was able to tackle the QB behind the line.
Here is the moment the QB makes his read. Notice how #51 has his hips completely underneath him. He is able to quickly move to contain the QB. The correct play would have been to hand off to the running back, due to the lack of commitment by the EMOL.
