Split Zone (like inside zone or zone read) entails all lineman taking a play side zone step, or stepping with their play side foot first toward where the run is designed to go. Like Zone Read, the end man on the line of scrimmage is left unblocked by the offensive line. However, the quarterback is not making a read on this defender; instead, an H-Back, Fullback, or Tight End will come across the formation for a kick out block, creating a natural crease for the running back to cut back. The kick block makes the play a bit like a trap. The running back steps downhill for the ball and has a 3-way go: continue outside (if every defender has been reached), plant his foot and press up field once defenders spill over the top, or see the cutback lane and attack the crease backside.

Split Zone creates a natural crease because inside linebackers must flow downhill play side. Meanwhile, the defender unblocked by the offensive line may see the play as zone read and play a feather technique to prevent the QB from keeping the ball. This gives the H-Back/TE a clear advantage, as he is coming to kick out the defender on his heels at full speed. This is likely what happened on the Seahawk Touchdown, with Luke Willson (#82) getting a clean shot at Clay Matthews:

The play is blocked exactly how a coach would draw it up, with both guards reaching play side and controlling the defenders in head up 2-techniques. The right tackle steps play side and has a relatively easy block on the defensive end/OLB, Julius Peppers. The center helps the right guard control the 2-tech and then continues to the closest second level defender. The left tackle steps down hard play side and is able to easily wash (#50) A.J. Hawk, the inside linebacker who has flowed play side far too much. Take note of what the pre-snap motion did: When Willson moves across the formation, A.J. Hawk steps two full yards to his right. This leaves him out of position and unable to recover.

Below is an example of a defense playing Split Zone more soundly:

Washington’s outside linebacker Perry Riley (#56) is head up on the guard, instead of a shade inside, where A.J. Hawk was washed inside. Riley diagnoses the play well and doesn’t step too far downhill or inside. Riley also gets help from #98 Brian Orakpo, who stonewalls the kick out block and makes the cutback crease very small. Running back LeSean McCoy has no choice but to press up field into a scrum for a yard. Note that the Eagles have 2 tight ends, thus condensing the box. While in shotgun, Split Zone may be best with a more spread look (3 WR 1 TE and 1 RB).

Split Zone can be run by offenses with no zone read element as well. While nobody would call Tom Brady a speed demon, the Patriots are successfully able to execute Split Zone below:

The Colts linebacker (#52) D’Qwell Jackson starts over the guard and is over aggressive downhill and inside, making it easy for the right tackle (#76) Sebastian Vollmer to wash him down. The kick out block is essentially a stalemate, but there is still a cutback crease for the running back.

Split Zone also gives offenses play action options, both from under center and shotgun. The blocking scheme remains the same for the offensive line, who must sell run. The kick out blocker attacks the unblocked defender but avoids him and heads to the flat. It’s a win-win for the offense: If the unblocked defender crashes down hard, the receiver will likely be wide open in the flat. If he feathers, the quarterback will have room to throw. The play will almost always end up going toward the quarterback’s throwing arm:

As seen above, the play action element of Split Zone can also be run with a WR/RB hybrid to maximize speed from route runners. From under center, Split Zone play action is more effective with the TE/H-back/FB because it looks more like a run. However, the play action element may be harder to run from under center because the kick out blocker could get lost while sifting through traffic. Below, Seattle is able to pick up a key first down on 3rd and short:

Overall, Split Zone is a great complimentary concept to both inside zone and the zone read. If linebackers are being over aggressive and making tackles downhill against inside zone, or read men are feathering against zone read, Split Zone is the way to counter. Once defenses are aware of Split Zone as a run, play action is the next progression. While the primary focus here was Split Zone from shotgun, other analysts have focused on Split Zone from under center.

WHEN SEATTLE HAS THE BALL

The zone run game has given the Patriots problems, most recently against Baltimore in the Divisional Round (24 carries for 129 yards). While Seattle primarily runs zone, they use more inside zone and cut defensive lineman less efficiently. Most teams who run the football well have a dominant offensive line; but this isn’t the case for Seattle. Marshawn Lynch’s “beast mode” runs overshadow the fact that the Seahawks offensive line isn’t overly powerful or big.

The Seahawks will likely see a variety of Front-7 looks from the Patriots, including a true 3-4, with Vince Wilfork (#75) playing a 0 technique, Alan Branch (#97) and Sealver Siliga (#96) at Defensive End, Rob Ninkovich (#50) and Chandler Jones (#95) at Outside Linebacker, and Jamie Collins (#91) and Dont’a Hightower (#54) at Inside Linebacker. Look for (#55) Akeem Ayers to also play some outside linebacker in this look. This defensive front gives both teams advantages: While the 3-4 gives the Patriots both athleticism and versatility with 4 linebackers as well as over 1,000 pounds of stout mass on the defensive line against the run, it undoubtedly sacrifices the ability to get any pass rush against Russell Wilson.

The chess game will be particularly important when the Seahawks are in the Shotgun. Because the zone read such a dangerous threat, how the Patriots respond to it will be crucial to the outcome of the game. Expect the Patriots to take away Russell Wilson on the zone read and make him hand the ball off nearly every time. The first way this can be done is the feather technique. Below is an example of the feather technique, where the last defender on the line of scrimmage (#58 Thomas Davis) makes Russell Wilson hand the ball off by slow playing the read. Meanwhile, all the defensive lineman rip to their right hard, making all gaps accounted for. Once Marshawn Lynch has the ball, Davis can fill in the last gap for a one yard gain. (This is against a 4-6 Bear look, which the Seahawks may also see.)

The problem with feathering or slow playing the Zone Read is that it can leave the last defender on the line of scrimmage in a passive position. It also leaves him susceptible to concepts, such as split zone (seen below) that look like zone read, but take advantage of the feather technique’s passiveness:

What the Patriots could also do is aggressively take away the QB run option from Russell Wilson by flying fast downhill and making Wilson make a read quickly. Below isn’t the same exact type of play, (Counter vs. Zone) but Terrell Suggs (#55 on Baltimore) shows how playing fast downhill at the Quarterback can disrupt plays as the unblocked last defender on the line of scrimmage:

Seattle could respond to this type of approach from the Patriots by moving to a double tight end set, making it more difficult for the defense to keep a defender outside of the Tight End, and making it more difficult to play the zone read aggressively. The look below gives Seattle 9 in the box against Carolina’s 7, and the Defensive End let’s Wilson get outside because he does not attack Russell Wilson’s outside shoulder:

With respect to the passing game, expect Darrelle Revis to match up primarily with Doug Baldwin and follow him around the field. Brandon Browner will likely cover Jermaine Kearse (#15) for some of the game, but also expect designated T.Y. Hilton stopper (#25) Kyle Arrington to get some time matched up against the speedy Kearse with Safety help. When Arrington is on Kearse, this could leave Browner to cover speedy Seahawk Tight End Luke Willson (#82).

The Seattle passing game vs. the Patriots secondary isn’t necessarily about X’s and O’s, but a game of attrition: the Patriots will likely sell out to the stop the run and try and contain Russell Wilson instead of outright rushing him. The Patriots secondary is able to cover for long periods of time, while Russell Wilson is excellent extending plays and finding open Wide Receivers. This is a strength on strength, and will likely decide the game: who can win the scramble drill– will New England be able to cover when Wilson extends the play, or will his Receivers find a way to get open?

WHEN NEW ENGLAND HAS THE BALL

The combination of two weeks to prepare and the simplicity of Seattle’s Defensive scheme should make for an interesting New England game plan. The 2012 Patriots vs. Seahawks game featured almost 60 throws for Tom Brady, a ton of empty formations and almost 400 yards passing (The most Seattle has given up in the Legion of Boom era). New England had success throwing underneath with various schemes including their Y-stick and slant/flat combinations.

On the other hand, if Seattle’s defense has any vulnerability, it’s that the Front 7 is slightly undersized and built on speed. New England could run right at the Seattle defense, as all of Seattle’s losses this season had their opponents rushing for 100 or more yards.

Overall, I anticipate New England will implement aspects of both game plans depending on down + distance and field position. Expect New England to swing back and forth between Empty sets and Power and Iso looks with multiple tight ends and Fullback James Develin (#46) isolated on Seahawks middle linebacker Bobby Wagner (#54). Running the ball will also test Seahawks All-Pro Safety Earl Thomas (#29) injured shoulder. Because Seattle plays so simple schematically, New England could attack and keep Seattle off balance by making the Seahawks defend two completely different styles of football. It also gives the Patriots flexibility to adjust to the scoreboard.

Seattle’s elite pass defense has struggled against a few concepts this year, including Post-Wheel, Switch Verticals, and Seams paired with out and ups:

These concepts all have something in common: It exploits the ultra aggressive nature of Seattle’s Cover 3, where Cornerbacks match vertical releases and essentially play man-to-man after 10 yards and also try to undercut seam routes. This puts immense pressure on the linebackers to carry wheel routes and double moves. Of course, Seattle will be well aware of this weakness. In order for New England to take advantage of it, the Patriots could include a play action wrinkle to freeze linebackers, as well as use Rob Gronkowski as a decoy. The play below is a perfect example: The top of the screen features Gronk running a seam route while Tight End Tim Wright (#81) runs a wheel route and is also wide open. If this type of play action can freeze linebackers, and Gronk draws the attention of the Deep 1/3 corner, the Patriots could find huge plays up the sideline:

The Patriots could also attack the seams, but must set up Shane Vereen, Julian Edelman, and Danny Amendola underneath first. The Patriots certainly looked to the San Diego vs. Seattle tape for hints on how to attack Seattle. Many point to Antonio Gates 3 Touchdowns that day, but Danny Woodhead and Eddie Royal had 11 catches that day and provided crucial 3rd down conversions. In the 2012 Seattle/New England game Wes Welker came up with 10 catches for 138 yards and a TD. (Precedent for smaller, shiftier receivers succeeding against Seattle). The following play is a great example of how New England can isolate the Tight End via the Dakota formation, attack the seams, but also open up a versatile running back underneath for a big gain:

If the Patriots can get Earl Thomas and Cam Chancellor to come up to play the underneath routes from Vereen, Edelman, and Amendola, they will be able to attack the seams. In the play below, Safety Cam Chancellor freezes up for just a split second to cover Panthers Running Back Jonathan Stewart (#28) out of the back field, opening up the seam behind him:

Finally, as I’ve wrote about before, the Seahawks seem to move Richard Sherman inside to the slot when they feel the biggest receiving threat is there:

New England can find out early in the game if the Seahawks will move around Richard Sherman by putting Shane Vereen or Rob Gronkowski on the outside with Julian Edelman in the slot. What they will do with this matchup depends on if Edelman can beat Sherman consistently. This will be especially interesting given Sherman’s arm injury.

SPECIAL TEAMS

One interesting statistic of note: Seattle Punter Jon Ryan allowed the lowest number of punts returned this year, while Julian Edelman lead the league with 19.3 yards per return. Look for this strength vs. strength match up to be a key factor in field position and impact the game in a big way.

WHEN GREEN BAY HAS THE BALL:

Green Bay cut the field in half when they chose not to attack the right side of the field to avoid Richard Sherman Week 1; Green Bay aligned #11 Jarrett Boykin to the right on the vast majority of snaps. The Packers must attack all parts of the field in order to be successful this week.  While the Packers will almost certainly line up #87 Jordy Nelson to the right more often, the emergence of rookie #17 Davonte Adams gives Green Bay a viable threat even when Jordy Nelson is on the left side of the field. However, attacking the right side of the field doesn’t necessarily mean attacking Sherman 1 on 1. Look for Green Bay to manipulate formations to move Sherman away from the outside most Receiver. Dallas was able to do this from a Trips tight formation, with the TE as the lone eligible receiver to the left, and 3 Wideouts to the right:

Sherman moves with Dez Bryant to the slot

This formation moves Richard Sherman to the slot against Dez Bryant. The Packers Wide Receiving core is deeper than the Cowboys’ WRs, and this alignment would put the Seahawks in a bigger bind than against Dallas. If Seattle aligns Richard Sherman over Jordy Nelson in the slot, Sherman is not at his absolute best without the sideline as a defender. On the other hand, if Sherman stays to the outside, Green Bay can use #18 Randall Cobb, Adams or Nelson on the right side of the field without ever testing Sherman. This play results in a 20+ yard gain with the whole field to work with, and a penalty on Sherman:

The trips tight formation makes Seattle’s Cover 3 slightly more challenging to play. The play above is Cover 1, and Green Bay should try to exploit it like Dallas did. Another way Green Bay can attack the right side of the field is by splitting either Running Back #27 Eddie Lacy or #44 James Starks out wide with Randall Cobb in the slot right:

Sherman aligns against Welker in the slot with the RB to the outside

In the picture above, the Broncos place a Running Back out wide to move Sherman to the slot. If Green Bay can manipulate formations to get Randall Cobb on Sherman, especially in the slot, this is the most favorable matchup for Green Bay. Like other big corners, the hardest matchup isn’t necessarily the best or biggest Receiver; in fact, the shiftier, quicker types give Sherman slightly more trouble.

As for the running game, Green Bay must establish it early. Eddie Lacy was unable to finish the game Week 1 with a concussion, but his presence will be huge on Sunday. He started off the game gaining yardage while breaking tackles and being agile enough to juke out the best safety in the NFL, Earl Thomas; no small task:

Runs like this are essential for multiple reasons: Green Bay will probably spend 95% of the game in either Shotgun or Pistol due to Aaron Rodgers’ hurt calf. The Packers must be able to run the ball regardless. Lacy is a versatile back: he is a viable threat in the passing game, can run defenders over, and also can make defenders miss. Look for Lacy and Seattle’s Cam Chancellor (#31) to provide some of the hardest collisions the NFL has seen all year. If Lacy can stay healthy for the whole game, look for the Packers to improve on the 16 point output from Week 1.

WHEN SEATTLE HAS THE BALL:

Seattle drove Green Bay crazy Week 1 with various versions of Jet Sweep and read option. However, with Percy Harvin long gone, Seattle will come up with new wrinkles to attack the Green Bay run defense. Green Bay’s run defense has improved greatly over the course of the season: Since Clay Matthews moved to Inside Linebacker, Green Bay is in the top-10 against the run. (GB was in the bottom 10 prior). Green Bay has also recently gotten major contributions out of Defensive Lineman #76 Mike Daniels in stopping the run. Daniels will sometimes be lined up against a hurting Max Unger (Seattle’s Center, #60) and could be the key to getting interior penetration against Seattle’s run game with efforts like this, causing Running Backs to hesitate and freeing up Clay Matthews from the middle:

This matchup is key and simply about execution, not X’s and O’s. Seattle will look to dominate the line of scrimmage and Daniels like in the Week 1 matchup:

Seattle will certainly use some read option, but look for them to use the split zone concept as well. Split zone may look like zone read and is meant to freeze linebackers, but the Quarterback is only a decoy as a running threat. It is blocked similar to Zone read in the sense that a defender is left unblocked at the snap of the ball and the Tackle can aggressively down block. However, a Tight End or fullback will come across the formation to block the defensive end or linebacker. The direction of the Running Back and the Quarterback’s action will make it look like Read Option, and create a natural crease for the blocker and the running back to cut back. Seen below is a Week 1 Split Zone run to perfection. Green Bay’s Clay Matthews (#52) plays this as zone read, only to be blocked completely out of the play by Luke Willson (#82) who is coming across the formation. Russell Wilson (#3) sells read option action, but is never actually a running threat:

Finally, when it comes to the passing game, look for the key matchup to be #56 Julius Peppers against banged up Rookie Right Tackle #68 Justin Britt. (If Britt can’t play due to injury, Alvin Bailey would be next in line). Peppers has been on fire recently, forcing fumbles from both Tony Romo and Demarco Murray last week. His pass rush ability must make Russell Wilson uncomfortable in the pocket.
