EFFECTIVE TEACHING: WHAT YOU DON'T TELL IS AS IMPORTANT AS WHAT YOU DO
Coaches need to understand that restraint in communication is crucial. Avoid rambling in meetings - once players have the information they need, stop talking. Over-explaining can actually hurt their performance.
LEARN BEFORE YOU COMPETE
This fundamental principle emphasizes that players must thoroughly understand concepts before being asked to execute them in competition. The learning process should happen systematically throughout the day.
CLASSROOM SETUP AND PEER LEARNING
Set up meeting rooms conference-style rather than traditional classroom-style. This allows players to see each other, prevents hiding, and creates peer accountability. When making corrections, everyone can observe, increasing the effectiveness through peer group influence.
Use discussion groups rather than lectures. Have players explain plays, protections, and techniques to each other. This participatory approach leads to 50% retention compared to just 5-10% from lecturing alone.
THE WALKTHROUGH: THE MOST IMPORTANT PRACTICE PERIOD
The walkthrough is the most critical period in practice - not individual drills as many line coaches believe. This is where players can perfect their footwork and angles without the chaos of full-speed competition.
The angle of departure from the line of scrimmage is the #1 fundamental in offensive line play. Few players can recover from leaving at the wrong angle. The walkthrough allows repeated, precise practice of this skill, resulting in 75% retention of material.
PEER COACHING
When players coach each other using your language and approach, let them continue without interruption. Players retain 90% of what they learn from teammates like Joe Thomas compared to coaches.
STRETCHING PHILOSOPHY
The speaker's experience with the Oakland Raiders: they eliminated team stretching, instead requiring players to prepare individually with trainers and strength coaches before practice. This approach resulted in the fewest soft tissue injuries in the NFL.
PRACTICE STRUCTURE: LEARNING THEN COMPETING
The progression moves from classroom to walkthrough to individual periods - all learning phases. Competition happens afterward in periods like inside run or team periods. Both players and coaches must compete during these competitive periods.
Block ANY Front the Defense Throws at You

SUMMARY OF COACHING VIDEO ON OFFENSIVE BLOCKING SCHEMES
This coaching video focuses on blocking fundamentals and game planning for offensive run schemes, with emphasis on inside zone concepts.
CORE PHILOSOPHY: STICK TO YOUR FOUNDATION
The coach emphasizes that while you'll need to make weekly adjustments based on opponents, your base blocking rules should handle any defensive front. If a team switches from a 4-down to 3-down front unexpectedly, your players should fall back on foundational rules that work universally. This prevents confusion and keeps players executing at full speed.
GAME PLANNING ELEMENTS
The presentation breaks down five key areas for weekly preparation:
Split flow and slider concepts help hold linebackers and prevent defenses from flowing full speed to the ball. Motion serves multiple purposes - pulling safeties out of position, affecting nickel/Sam linebackers, and getting pre-snap coverage indicators. Formations should be selected based on film study to get optimal blocking angles and the defensive alignments you want to attack. Personnel groupings must get your playmakers on the field, whether that's living in 20/21 personnel with two running backs or other combinations that maximize talent.
PROTECTING THE RUN
Against boxes where defenders outnumber blockers (5 on 5 becoming 6 in the box), you need answers - RPOs, reading defenders, bubble screens, or quick slants. The scheme must account for that extra defender.
11 HATS PRINCIPLE
Every player has a critical job regardless of position or location. The backside receiver blocking the field safety, the quarterback selling the read to slow linebackers, the tight end executing the cutoff block - all 11 players matter. One missed assignment can be the difference between a 20-yard gain and a touchdown.
KEEP IT SIMPLE
Don't overthink weekly game plans or abandon your identity. Players need to play fast without thinking. Stick to your rules, get pre-snap reads, and execute. Balance simplicity with avoiding predictability.
INSIDE ZONE BREAKDOWN
The video shows multiple examples from 11 personnel, demonstrating how to handle six-man boxes through read concepts. When the sixth defender plays outside, hand the ball off into a 5-on-5 advantage. When he triggers inside, throw the RPO. The film shows excellent combo blocks with proper landmarks, vertical movement, and second-level finishing.
How to DESTROY Zone Read at the Edge (D-Line Run Block Destruction Breakdown)

DEFENSIVE EDGE MECHANICS: ZONE READ TECHNIQUES
This coaching clinic focuses on teaching defensive ends proper technique for defending zone read plays and option football. The core philosophy centers on reading blocks, maintaining proper positioning, and executing two key techniques: smash and squeeze.
FUNDAMENTAL STANCE AND READ PROGRESSION
Defenders should use an inside foot back stance when coming out of their stance. Upon seeing a down block by the offensive tackle, take eyes down the line of scrimmage while maintaining a near foot compression stance - similar to a tackling position but staying square to the line. The read progression follows three levels: level one (offensive lineman), level two (off-ball players), and level three (quarterback mesh point). Critical rule: never cross the line of scrimmage when engaging blockers, as this gives up blocking surfaces and eliminates lateral pursuit ability.
SMASH TECHNIQUE
The "smash and sneak" technique involves placing two hands on the offensive tackle - inside hand on outside number, outside hand on hip - and pushing him down to restrict the gap. This is primarily used for B gap bubble situations with gap exchange schemes. The defender takes the dive first, then plays the quarterback. When a puller or kickout blocker appears, the defender executes a "spill" move by getting vertical up the field through the blocker while keeping shoulders square - never turning sideways or trading one-for-one. This technique is effective against counter plays, split zone, and inside zone schemes.
SQUEEZE TECHNIQUE
Squeeze technique uses one hand on the offensive lineman's hip instead of two hands, allowing the defender to stay close enough to tackle anything off the blocker's backside while playing quarterback-to-dive assignments. This is typically used on the three-technique side or when a linebacker ("buddy") is blitzing the B gap. The defender maintains eyes down the line and keeps toes on the line of scrimmage, making this effective against stretch plays and outside zone runs while maintaining proper leverage to force early pitches.
KEY COACHING POINTS
The mantra "eat ends, attack tackles" emphasizes aggressive engagement. Defenders must work gap exchanges with linebackers or safeties, stay disciplined with hand placement and foot positioning, and trust their eye progression to react to multiple threats including dive, quarterback, and pitch options.
Master 2-Minute Drill: Game-Winning Situations & Practice Plans
Brad Aoki, Asst Coach, USC
Full video on Glazier Drive: Situational Football for QBs: Thriving in the 2-Minute Drill
KEY SITUATIONS COVERED
MUST - Plays where the clock must stop (no sacks, no in-bounds tackles). Used when preserving timeouts is critical, typically with limited time remaining and needing to save a timeout for a field goal attempt.
SINGLES - One-read plays where the QB throws if open or takes a quick incompletion to preserve time. Critical when you have 8-10 seconds left and need either a score or to set up a field goal.
MILK - Tempo change after gaining a chunk of yardage, slowing down the operation to avoid giving the opponent the ball back with time remaining.
DROP - Quick completion where the receiver immediately goes down. Used with 9-26 seconds left when you need a short gain to reach field goal range. Important coaching point: on fourth down, the receiver must secure the first down before going down.
CLOCK PLAY - Standard spike play with specific rules: two-second runoff, outside receivers run verticals, and QB must take a shot to the end zone if under three seconds remain.
SCORE CONCEPT - Empty formation where everyone runs to the end zone. Used when two seconds remain after a first down (not enough time to spike), or as a clock alternative inside the 15-yard line between 26-14 seconds (only bleeds two extra seconds).
PRACTICE RECOMMENDATIONS
The video emphasizes weekly competitive two-minute scenarios (8-10 plays starting in minus territory), plus "mini two-minute" drills (2-3 play scenarios in plus territory) that maximize reps and teaching while minimizing contact. These shorter scenarios allow 5-6 different situations in just 10-12 plays.
5 Non-Negotiable Linebacker Drills Every Program Needs
AJ Cooper, LB Coach, Arizona State
Full video on Glazier Drive: LB Everyday Drills
LINEBACKER FOOTWORK AND AGILITY TRAINING
This coaching video focuses on essential linebacker footwork drills and techniques, emphasizing that footwork is the most important skill for linebackers.
V DRILL (EDDD WARM-UP)
The V drill is designed to keep linebackers' feet active and works at 45-degree angles forward and backward. Key coaching points include maintaining a wide base, avoiding heel clicking, and keeping feet active. The coach emphasizes that linebackers should move together like "dancing partners" in a 4-2-5 system.
SHOOTS AND CONES AGILITY DRILL
This daily drill mimics running back movements for various schemes (inside zone, mid zone, gap schemes). Critical elements include maintaining low hip level throughout the drill, keeping hands up to destroy blocks, and ensuring hip level remains consistent whether in or out of the shoots. Players work on shuffle steps for inside zone with wide feet that don't come together, planting off the outside foot, and finishing with proper tackling fundamentals (same foot, same shoulder).
CLEAR CLOUDY DRILL
This is a major teaching tool used almost daily during spring and fall camp, and weekly during the season. The drill focuses on matching the running back's path with proper footwork. Players learn to recognize different schemes (zone, mid zone, counter, insert, split zone) and adjust their steps accordingly. Key techniques include two-step crossovers for wide tracks, shuffle steps for inside zone/duo with square shoulders, and one-step crossovers for mid zone schemes.
COACHING PHILOSOPHY
The coach stresses that individual drill performance directly correlates to game performance—if players struggle with footwork in games, the issues will show up in individual drills. Every rep should be treated as a tackling rep with proper finishing technique.
