Player Personal in the 4-4 Stack Defensive Ends should be the best athletes main requirements are toughness and agility take the best of the two defensive ends and place him on the left side of our defense should be a strong tacklerDefensive Tackles the largest players on the front four usually are placed at DT their job is basically to control the area inside the offensive tackleLinebackers Outside linebackers o position demands two of the squads best athletes o they do not have to be large, but must be strong enough to meet an end sweep effectively o outside linebackers will have to make adjustments to some offensive formations o must have the ability to move quickly Inside linebackers o needs to be strong enough to help stop the inside running-play o agile enough to cover the middle area whining playing zone pass defense o does not have to be as fast as the outside linebackerSafety Men Left and right safeties o main requirement is speed o we like to use tall boys here when they are available o they should be able to play a wide flanker or split end man-to man o must learn the sideline tackle and how to make the sideline work for them and serve as a twelfth man o they should be sure if not brutal tacklers Middle safety o last man between the offense and the goal line o chose this position with extreme care o should be the most dependable tackler of the three safety men o he should learn to read the Play quickly o play pass defense first and run second o he is the center fielder o he should always point out formations 3 4. Quick review to help in the placement of personnel: 1. Get as much speed in the lineup as possible. 2. Look for aggressive players who can react well and are willing to get themselves emotionally ready to play football. 3. Place the most agile of the front four players on the outside of the front four. 4. Place the larger and slower front four players at the two inside tackle positions. 5. Two of the best athletes on the squad should be placed at the outside linebacker positions. 6. Inside linebackers should be able to stunt quickly across the line of scrimmage and should be good tacklers. 7. Speed is the key in selection safety men. 44 Stack Numbering System and Stunts Each of the four stack units is numbered. The left outside front four man and the left outside linebacker together make up un Unit 1. The left inside front four man and left inside linebacker together make up Unit 2 The inside front four man and the right inside linebacker together make up Unit 3 The right outside front four man and the right outside linebacker together make up Unit 4. Each Unit is responsible for covering two offensive gaps. o Units 1 and 4 are responsible for the C and D gaps o Units 2 and 3 are responsible for the A and B gaps. Each unit can work separately or with another unit to protect those gaps. Gap Responsibilities DO C OB OA X A O B O C O D4 5.

Basic Responsibilities by Position Defensive Line Defensive linemen are charged with establishing a push to force the offensive line to set their blocks, penetrating and securing assigned gaps, and providing an initial pass rush in the event of a pass read. No defensive lineman can ever allow themselves to be blocked by fewer than two offensive players. Defensive linemen must always continue to gain ground into the offensive backfield.Linebackers Linebackers are responsible for securing alternate gaps to the defensive linemen, for covering running backs in man-to-man pass coverage (Cover-1, Cover-0), covering the short zones in zone pass coverage (Cover-3, Cover-2), and for providing secondary pass rush in the event of a blitz. Outside linebackers are responsible for outside contain, and must never allow the ball to cross their outside shoulder at all times. Inside linebackers are also responsible for watching for screens and draws on passing downs.Defensive Backs Defensive Backs are the primary source of pass coverage downfield and a secondary run support. As such, they will not be charged with any blitzing or rushing responsibilities. They must roll towards the ball once it heads to the sideline, and provide outside-in leverage on the ball to force it back to the interior defenders. The Free Safety is the final line of defense and must play to keep all members of the offensive unit in front of him at all times.7 8. Basic Alignment Rules Overview After the shift on quarterbacks second syllable of cadence, the defense will adjust their alignment to the front called from the sideline.Front Calls Each defensive front will be called with a term. These will be signaled in from the sideline before each offensive play. All alignments begin with the determination of the strength of the offensive formation using the following rules: 1. 2. 3. 4.Strength of offensive line (tight end location.) Strength of offensive backfield (two running backs on the same side) passing strength of offensive formation (trips set) If the offensive set is balanced, the strong side may be determined to be the field or based on offensive tendencies.Alignment PlayersAlignmentAssignmentSDEHead up on tight endC-GapSDTHead up on strong side guardA-GapWDTHead up on weak side guardA-GapWDEOutside shade of weak side tackleC-GapThe inside linebackers align using the following rules: 1. When the man in front of me is head up, I stack behind him. 2. When the man in front of me moves to shade, I shade the opposite way.8 9. Always Rules for Alignment The following rules are always in effect: 1. The strong side defensive end will always align head up on the tight end. 2. All defensive players will always have responsibility for the gap in which they are aligned, unless changed by a stunt. 3. Defensive linemen will always have the inside gap when aligned head up, unless changed by a stunt. 4. Linebackers will always have the outside gap when stacked, unless changed by a stunt. 5. Defenders will always be responsible for only one gap. (We never play head up and two-gap.)Alignment Depths and Positions PositionAlignmentDepthSDEHead up on TEOn LOSSam1 off LOS, 3 outside SDEs heels1 yd or by D/DSDTBy front callON LOSLionBy front call3 yds or by D/DRamBy front call3 yds or by D/DWDTBy front callOn LOSWill2 off LOS, 1 outside WDEs heels2 yds or by D/DWDE6, OR head up on 2nd TEOn LOSLCCoverage call6-7 or by D/DRCCoverage call6-7 or by D/DFSCoverage call, usually to strength9-12 or by D/D9 10. Blitz Package Overview Each defensive player is responsible for learning only two gap assignments: his base assignment and his stunt assignment. All combo stunts are merely various two gap assignments for two or more players.Always rules for Stunts The following rules are always in effect: 1. 2. 3. 4.A player not involved in a stunt always plays base against the offensive play. Players will always stunt through their assigned gaps. The weak side man always goes first when players cross. Stunts will always be executed by linebackers. (We do not stunt the secondary.) Basic StuntsX Stunt o The most effective of our penetrating stunts. o It involves both the front four man and the linebacker in the same unit. o Linebackers will give a verbal command of go right or Go left o The X stunt can be run from the stack position or from many different unit positions. o Two or more units may X at the same time.There are two important coaching points to consider when teaching the X Stunt. 1. Make sure that the linebackers do not give away their intention to stunt by moving too quickly towards their gap before the ball is snapped. 2. Make sure the units do not get patterns set up between the front four man and his linebacker. Offenses will be able to pick up on this. Gap Stunt o The Gap is a stunt performed only by a front four player o The Gap stunt is used when we want penetration of the gap, but we want the linebacker to stay back. Do not penetrate past the ball. o There are two calls The Gap In call means in toward the center. The Gap Out call means away from the center. The All Gap out call is an all gap out call The All Gap In call is an all gap to the side.10 11. Slant Stunt o This is an excellent way to keep the offensive tackles or center off our linebackers. o Front four needs to line up a little deeper for this stunt. o Step towards the offensive man with your lead foot and drive through the helmet of your opponents helmet. o Keep your feet wide o We do not want penetration. o Linebackers must loosen up slightly and move laterally away from the slant. This is because he now has slightly more territory in his area to cover. calls are the Unit number and Slant Right or Left or Slant Strong or Weak Loop Stunt o Very effective in stopping the off-tackle play. o If we are running a Loop stunt we will slant into the offensive tackle with our 1 and/or 2 Unit front man. o The Unit 2 and/or Unit 3 linebacker no fires off the tail of the Unit 1 and/or 4 front four man and heads straight for the offensive off-tackle hole Fire Stunt o We use this to fire a linebacker across the line of scrimmage, but keep the front four man playing Basic. o Calls are the Unit number and Fire In or Fire out or All Fire IN or All Fire Out. o On this stunt we want the front four man in the firing unit to
