Sunday night against the Cincinnati Bengals. To date Limited Reggie Ragland Jersey , they are 4-3 in the red-on-red look.Let’s take a look back at those seven games:September 15, 2013 vs. Dallas CowboysPhoto by Kyle Rivas/Getty ImagesChiefs 17, Cowboys 16 | BOX SCOREThe Chiefs won their second of nine straight games to begin the season, as they debuted the red-on-red look for the first time. Alex Smith, in his second game as a Chief, threw for 223 yards and two touchdowns to defeat Cowboys quarterback Tony Romo. Wide receiver Dwayne Bowe had the go-ahead touchdown catch. As seen above, safety Eric Berry recovered a Cowboys fumble caused by linebacker Tamba Hali during the game.September 29, 2014 vs. New England PatriotsPhoto by Dilip Vishwanat/Getty ImagesChiefs 41, Patriots 14 | BOX SCOREThe Chiefs improved to a 2-2 record in a blowout of the New England Patriots on Monday Night Football. Running back Jamaal Charles had three touchdowns for the Chiefs in his return from injury, and the Chiefs picked off Tom Brady twice—including the 39-yard touchdown off an interception by safety Husain Abdullah (as pictured). This was the same night the Arrowhead Stadium crowd set the Guinness record for the loudest crowd roar at a sports stadium. November 30, 2014 vs. Denver BroncosPhoto by Jamie Squire/Getty ImagesBroncos 29, Chiefs 16 | BOX SCOREQuarterback Peyton Manning continued the trend of the Broncos’ dominance of the Chiefs with Denver’s sixth straight win over Kansas City. The Chiefs’ first loss in the red-on-red uniforms dropped them to 7-5 on the season, and the Chiefs would go 2-2 the rest of the way to miss the postseason for the only time in Andy Reid’s duration as Kansas City’s head coach.September 17, 2015 vs. Denver BroncosPhoto by Peter Aiken/Getty ImagesBroncos 31, Chiefs 24 | BOX SCOREThis is not a fun game to remember if you’re a Chiefs fan. The Chiefs and Broncos met at Arrowhead Stadium in a Thursday Night Football thriller, and Kansas City led by a touchdown with less than a minute to go. Peyton Manning and the Broncos tied the game at 24 with less than 40 seconds left, and the Chiefs got the ball back and were seemingly trying to kill clock leading into overtime. Running back Jamaal Charles took the handoff and fumbled the football, and Bradley Roby picked it up and ran it 21 yards back for the game-winning touchdown.December 8, 2016 vs. Oakland RaidersPhoto by Jamie Squire/Getty ImagesChiefs 21, Raiders 13 | BOX SCOREThe Tyreek Hill-chant game and Thursday Night Football. With the Chiefs already up 14-3, the Raiders punted to rookie Tyreek Hill. Hit was tackled, but the Raiders were called for a penalty on the play, setting up a re-kick. For the first time, the Arrowhead Stadium fans chanted his name prior to a punt— “Tyreek, Tyreek, Tyreek.” Hill returned the second try for a 78-yard return touchdown, and the Chiefs defense held off the Raiders for their 10th win of the season and control of the AFC West division.

It was the second game in connection with the NFL’s color rush initiative. The Raiders entered the game on a four-game losing streak against the 5-1 Chiefs. It was back and forth most of the game, with the Raiders rallying back from a nine-point deficit in the final quarter. With Oakland on the Kansas City doorstep down six points, the Chiefs took back-to-back defensive holding penalties Orlando Scandrick Jersey , extending the game. On the Raiders’ third-straight untimed down, Derek Carr hit Michael Crabtree in the end zone for the win. This is the only road game in which the Chiefs have worn the red-on-red uniforms.December 16, 2017 vs. Los Angeles ChargersPhoto by Jamie Squire/Getty ImagesChiefs 30, Chargers 13 | BOX SCOREThe Chiefs wore red-on-red uniforms for their Saturday night game against the Los Angeles Chargers. After the Chargers took a brief three-point lead in the third quarter, the Chiefs never looked back. Alex Smith threw for 231 yards and two touchdowns and Kareem Hunt had 155 rushing yards and two total touchdowns as the Chiefs all but wrapped up the AFC West division at 8-6. This game was another key in Patrick Mahomes getting his Week 17 opportunity (with playoff position locked up), one that led to the Chiefs changing quarterbacks this past offseason.How will the Chiefs do in their red-on-red uniforms Sunday night? The Baltimore Ravens currently boast the top-rated defense in the NFL by many metrics including points against, yards allowed and points per drive. They have given up 24 or more points only three times this entire season and haven’t done so since late October against the Carolina Panthers. The Kansas City Chiefs offense is one of, if not the best, in the NFL, ranking first, second or third in all of those same categories that tout the Ravens as the top defense. The Chiefs haven’t scored 24 or less points a single time this season and only under 30 points twice. This game is two units of football that are objectively in the elite category against each other.This is going to be a massive chess match between an offensive coaching staff that has excelled picking apart defenses and generating favorable matchups and a defensive coaching staff that has found a way to force nearly every offense out of rhythm. Andy Reid and Patrick Mahomes spoke to the media about how this Ravens’ defense will be a huge test. Both Mahomes and Reid touched upon the Ravens unique style of defense and the pressure it places on a quarterback:With the respect the Chiefs have for the Ravens defense and the praise for the Chiefs offense was sent back to them from the Ravens staff, it’s time to head down into the AP Laboratory and break down this vaunted Ravens defense. Baltimore Ravens defensePhoto by Kevin C. Cox/Getty ImagesPersonnel preferencesThe Ravens, like much of their defense, have a slightly different way of choosing their personnel packages. They look to match offensive personnel, but it’s equally important to them to rotate players often and have ever-changing fronts. They have a deep rotation of five defensive linemen that all play about half the snaps to keep them fresh but they also utilize larger EDGE players. These bigger EDGE players blend a 3-4 outside linebacker and a 4-3 defense end, which allow them to lose an interior defensive lineman in a nickel package but still play without a “light front.”Their secondary rotation is heavier on the cornerbacks than it is on safeties, which does allow more flexibility in their coverage. Normally, a team opts to bring a safety into the nickel, especially heavy nickel, in order to play the run and pass equally well. Baltimore, however, often plays with that heavier front and asks them to occupy space and blockers. This frees up the linebackers to roam freer against the run placing less stress on the nickel back in the run game. Pass defenseThe downside to this heavier front, especially one that two-gaps so often, is that they’re one-on-one pass rushing ability isn’t great. Their pressure from the front four or even five is often a slow bleed that compresses the pocket rather than players quickly beating their blocker. To counteract this, the Ravens have a very creative and deep blitz package that they dial up well. They aren’t scared to blitz on any down or distance or to call a Cover-0 (man coverage on every receiving option, everyone else rushing the passer) or bring a number of defensive backs. Some blitzes are designed to be quick and off the edge while others involved delays, stunts and twists. Matt Judon and Terrell Suggs provide the most consistent pass rush for the Ravens, both coming off the edge, but it really is a team effort on the pass rush. Their coverage behind the pass rush is most often man with a single-high safety, but they are not married to the coverage. They can go an entire game man to man only to drop into a static Cover-2 on an important third down or visa versa. Their coverage shells really are multiple and not only change within a game, but also week to week, their identity may alter as well. The CB tandem of Marlon Humphrey and Jimmy Smith challenge wide receivers throughout their routes but also play very aggressively in all coverage, allowing big plays from time to time. Eric Weddle usually mans the deep post and while he is an extremely good and heady player, he’s lost a step since he last played within the AFC West. Run defenseThe Ravens’ run defense is one of the last remaining two-gap systems that ask the interior defensive linemen to control the gaps to either side of their blocker. There isn’t a ton of penetration by their line of scrimmage players, but they do a good job eating up single and double blocks Authentic Xavier Williams Jersey , allowing their linebackers to flow to the ball cleanly and quickly. It takes a ton of patience as well as discipline to execute this gap control system and it has bit the Ravens a few times this year. Brandon Williams is the star in the middle of this two gap system with surprising quickness for his size. Behind him, CJ Mosely is a rangy linebacker that can come downhill with the best of them. When Mosely and rookie LB Kenny Young are kept clean and allowed to pursue, they are hard to escape.The gameplanBeat the pressureThe Chiefs’ most important task will be handling the pressure packages of the Ravens and getting their protection calls right against the blitz. Whether they plan to attack the blitz with quick passes in the holes vacated or try to protect the blitz and get them over the top, the key will be to handle the pressure. The Ravens telegraph this blitz in subtle ways but it’s the little stuff the Chiefs will have to pick up on. With six players crowding the LoS, plus a Mike linebacker, the protection already has to account for seven potential rushers. This means that the running back is going to responsible for a guy/gap and the quarterback will be responsible for at least one player who will be unblocked if everyone rushes. It will be up to Mahomes and Mitch Morse to get these protection calls correct, then up to Mahomes to get through his reads before the unaccounted for player can reach him. Coverage shell gameWhen blitzing or not, the Chiefs’ next most important goal has to be to identify the coverage and properly attack it. The Ravens, unlike many teams, don’t follow a specific pattern, so pure man beating or zone beat route combinations across the board aren’t always doable. The Chiefs will need to split the field into a man-beating concept and a zone beating concept opposite of it. Patrick Mahomes will then have to read the defense pre and post-snap to determine where he starts with his progressions. This is a Tare route combination, it essentially has a clear-out fade with a two-level read underneath it for the quarterback. The fade takes away any player with a deep-zone responsibility, trying to create stress on the flat or buzz defender underneath it. On the back side of the passing strength, trips receiver alignment is a tag for the X wide receiver based on how the cornerback plays them. It’s often a slant but can be one of many man-beating routes. The Oakland Raiders ran this from a trips formation with a tight split that actually created a little bit of a natural rub which made the combination equally good against man and zone. The Chiefs would be smart to incorporate plays designed to take advantage of both coverage shells whether splitting the field in half or using these bunched sets to get natural rubs for what is normally a zone beating route. Get all the informationTo help Mahomes with the identification process, the Chiefs should use pre-snap motion to determine man or zone coverage. Additionally, they should manipulate the pre-snap alignment to help force the Ravens into showing their coverage. The use of trips, stacks and tight formations will force defenders to change their alignment which can key their coverage call. The Chiefs should also dial back into the empty sets and get all five receivers out of the backfield. The availability of Sammy Watkins plays a large role in how effective the Chiefs empty sets can be, but even without him, they should look to around 10 snaps from empty. Not only does it force the Ravens to show man or zone, it also puts all the defenders in space. The Ravens defense is very stout and physical but does have some weakness to overall team speed. Going empty should help the Chiefs take advantage of that as well as initiate natural rub routes within the context of the route combinations. Know the Ravens’ weak pointsThe Ravens defense fares very well against outside receivers or what is termed a team’s top two receivers, as well as running backs in the passing game. Where they struggle a quite a bit more is with a third wide receiver, often when lined up in the slot and tight ends.The Chiefs should heavily rely on Travis Kelce, esepicially when the Ravens try to get Kenny Young in coverage against him. Beyond Kelce, the combination of Watkins and Chris Conley should find some space to work over the middle as well as Demetrius Harris getting loose for a second game in a row. Use over-pursuit against themWhen a defensive lineman is looking to control two gaps, he can often disengage to the gap a running back looks like he is aiming for. The linebacker behind them is also in control of attacking that gap, so you end up with two players in the same gap. It works great when the runner actually goes to that gap, but a savvy running back with good vision sees this happen they can cut against the grain. Baltimore forces a ton of negative and short plays to the play side of the run action but a running back, who stays patient and presses the line of scrimmage without committing to the hole can open a cut to the backside of the run. The nose tackle and back-side defensive end read the zone step from the blockers and try to attack the blocks directly, even at the lateral angle. This ensures they can release, or attempt to release, both to the play side of the blocker and the back side rather than get sealed away from the play. What can happen is a good offensive linemen will drop their play-side shoulder and hip and try to torque you further play side if they know they can’t seal you away from it. They are essentially washing you down the line of scrimmage allowing the running back to cut off their backside hip. As a running back, you can’t explode into the first daylight you see but rather be patient pressing up to the line of scrimmage and forcing those two-gapping defensive linemen to commit before you do. The bottom lineThis is a very good Ravens defense that is going to test the Chiefs offense at all levels. The gameplan is more about identifying their coverage in various manners and how to disrupt their physical play rather than a specific attack. The reason for this is because of how often the Ravens defense changes from week to week or drive to drive. Due to that multiple scheme and varied philosophy, the Chiefs have to focus on identifying the coverage before they can commit to a plan of attack. Team speed is often what gives the Ravens the most trouble through the years and that’s something the Chiefs do have in spades. As Reid and Mahomes spoke about, this is a playoff type of test for the Chiefs offense.
