Pass Protection:Schemes and Technique
The complete coach's guide to pass protection: schemes (BOB, slide, half-slide, cup), technique by position, and how to defend modern pressure looks.
Pass protection wins football games. A great QB with a broken pocket throws like an average QB; an average QB with a clean pocket throws like a great one. The OL coach's job is to put the QB in a clean pocket on third down.
This guide covers protection schemes, position-by-position technique, and the answers to modern pressure packages.
The five protection schemes
**BOB (Big-On-Big)**: the OL takes the four interior rushers; the back has the unblocked LB. Simple, durable, but vulnerable to overload blitzes that bring more than the back can handle.
**Slide**: the entire OL slides one direction post-snap. Used to handle expected pressure to one side. The QB rolls opposite to give himself a runway.
**Half-slide**: the OL slides one direction, the back BOBs the backside. The most-used modern protection because it has built-in answers to most blitz looks.
**Full-slide with chip**: 5-man slide with the back chipping a wide-9 DE before releasing. Used vs. dominant edge rushers when the offense doesn't trust the tackle to win solo.
**Cup**: 7-man pocket with both backs in protection. Used on max-protect concepts when the offense needs 3.0+ seconds for the route to develop.
Technique by position
**Tackles vs. wide-9 DE**: the kick-step has to gain depth and width simultaneously. The hands set the rep — independent strike, inside hand to the chest plate first. Lose ground and the DE bends the corner; lose width and the long-arm wins.
**Guards vs. 3-tech**: short-set or jump-set to take away runway, then anchor with low pad level. The 3-technique's bull-rush is the most common interior win — anchor and inside-hand placement defeat it.
**Centers vs. nose**: the center's fight is the punch-and-pull. Get hands inside, control the rusher's chest plate, lock him into the gap. Never allow the nose to swim across the center's face.
**Backs in protection**: BOB reads inside-out, near to far. Stay square, break down 2 yards in front of the rusher, strike with two hands to the chest. Lower man wins.
Defending pressure
Modern defenses live on disguise. The mug front shows 6-7 rushers and brings 4. The creeper drops a DL and brings a 5th from the secondary. The simulated pressure looks 5-man and is actually 4-man with a non-DL rusher.
The protection answer is the **pre-snap declaration**. The QB and the C identify the Mike (the most-likely rusher), and the OL's slide direction is built off that call. If the actual rusher isn't the declared Mike, the protection has a built-in adjustment — usually the back picks him up.
The hot route is the offense's last line of defense. If the protection is busted, the QB needs a 1.5-second throw to hot. That's why every modern offense has a slant or quick-out tagged to every protection — including ones designed to hold for 3+ seconds.
