Terry Heffernan, the offensive coordinator and offensive line coach at Stanford, has heard the same hallway conversation everywhere he’s coached: it’s the middle of the week, someone’s just watched the opponent’s tape, and a coach walks down the hall to tell him, “holy smokes, we’re going to have a hard time blocking this dude.” Heffernan’s argument isn’t that you need a clever answer in that moment. It’s that if you’re building your answer in that moment, you’ve already lost the argument — and the fix isn’t one idea, it’s a whole vocabulary you should have installed months earlier, built around a distinction most O-line rooms never bother to make.
Every staff has some version of the six-man protection drop-back world: five linemen, a quarterback, and nothing else, snap after snap, in every critical passing situation. It’s simple to call, simple to install, and Heffernan thinks it’s a trap. “If you go into the season saying you are going to be in the six-man drop back in all critical pass situations and you’re never going to help your tackles with a chip or a nudge, you don’t have a movement, right, that you’re going to be able to take advantage,” he says. Push it further and the stakes get sharper: “when you go into a just a drop back world, you’re setting your group up for failure.”
That’s not a call for more protectors — Heffernan is just as interested in the protection you can build for free. But the real weight of his argument sits somewhere less obvious: two words that get thrown around a line room interchangeably, “chip” and “nudge,” describe two fundamentally different promises to your tackle. Confuse them, or worse, never define them at all, and you haven’t actually helped anybody. You’ve just added a word to the call sheet.
How Can an Inline Tight End Help Pass Protection Without Adding a Protector?
Before any of that, Heffernan wants coaches to notice the protection they can buy without spending a body. It starts with where you line up your tight end. “Let’s talk about the advantage and use of an inline tight end release,” he says, walking through tape from his time with the Lions. Split the tight end out and you give the defensive end room to work — space to loop, space to counter, space to feel out your tackle before he ever gets his hands on him. Put that same tight end on the ball in the same pass concept, and something changes before the snap even happens: “you’ve tightened the alignment of the defensive end.” The rusher has less grass to play in and less time to disguise what he’s doing, and your tackle benefits from that compression without anyone else touching him. Heffernan shows the result on tape — a defender forced tighter by the formation, and a tackle who “was able to get my hands on and quickly crowd set, take advantage of the tight alignment” before the rusher could generate any force at all.
The appeal of this option is that it costs nothing. “It can benefit your tackle without taking another protector out, without chipping, without nudging,” Heffernan says. If you know you’re facing a rusher who thrives on space — someone who wants to work an inside move off a wide split — the fix might not be adding a body to the protection count at all. It might just be moving the tight end four yards closer to the ball on the concepts where you can afford to.
That’s the free option. Everything else Heffernan talks about costs you something — a body, an assignment, a piece of your route concept — and that’s where the real distinction starts.
What Is a Nudge in Pass Protection, and Why Is It Guaranteed Help?
Here’s the sentence that does the real work in Heffernan’s talk, and it’s easy to miss because he says it almost in passing: “the tight end does not have a protection responsibility in a normal six-man protection, right. So that is a guaranteed nudge to that nudge side.”
Sit with that for a second, because it’s the whole idea. In a standard six-man protection, the tight end who releases into a route isn’t protecting anybody — he was never in the count. So if you tell him to nudge through the widest rusher on his way out, there is no competing job pulling him away from that assignment. Nothing can override it. Your tackle isn’t hoping for help. He’s getting it, every single time that call is made, because the guy delivering it has no other responsibility that could take it away from him.
That’s what makes a nudge a guarantee, and it’s why Heffernan tells his tackles to set accordingly. A tackle who knows the nudge is coming can play with an edge he wouldn’t otherwise have — he can play a little more aggressive to the inside, a little less worried about the speed rush around him, because the widest threat is getting touched no matter what. Heffernan shows this with a tight end motioned back to the formation before the snap: “The tight end is going to nudge or block through the widest rusher. So, if the nickel comes, that would be the nickel… If the DN plays up the field, we can do that.” Whichever rusher shows up widest, the tight end has him — and because that’s certain, Heffernan can ask his guard to play differently too: “he should drag hand more on this three technique… the more you can benefit your guard by drag handing that, all right, we can shore up our whole protection by taking advantage of that nudge.” One guaranteed nudge doesn’t just help the guy it’s aimed at. It lets the whole protection lean on it.
What Is a Chip in Pass Protection, and Why Is It Only Conditional Help?
Now put a running back in that same helping role instead of a tight end, and the guarantee disappears — not because the back is less capable, but because he still has a job. “The running back does still have a protection responsibility in the chip protection,” Heffernan says. Before he’s a helper, he’s an insurance policy against a blitzer. If a linebacker comes, the back has to be there for him first. The chip on the defensive end only happens if nobody else needs him more.
That changes the entire coaching point for the tackle. “To me, the tackle cannot anticipate that,” Heffernan says. “That’s extra benefit, extra gravy, right, where the running back can come help your tackle as he releases.” Gravy is the right word for it, because gravy is good when it shows up and you don’t build the meal around it showing up. Heffernan is explicit about what this means for technique: “Our tackle’s got to set it true because if 25, this linebacker blitzes, all right, that running back has a protection responsibility.” Set true means set like the help isn’t coming — full width, full patience, no leaning on a chip that might get pulled away by a blitz call the tackle can’t see. If the chip arrives, it’s a bonus, and Heffernan will happily take it: he wants “the running back’s taking the speed rush out of the equation,” and he’s fine giving up a clean kill shot on the rusher to get it — “we’d love the shoulder blade to go through that guy, but not at the cost of knocking him across our tackle space.” But the tackle who was coached correctly never counted on that shoulder blade showing up in the first place.
That’s the whole distinction, and it’s worth saying plainly because most rooms never do: a nudge changes how your tackle should play, because it’s a promise. A chip doesn’t change how your tackle should play at all — it’s a bonus he happens to get sometimes. Call them the same thing, or worse, never separate them out loud, and you’ve told your tackle to expect help from a source that owes him nothing.
How Should Coaches Build Chip and Nudge Calls Into Their Protection System?
Once you’ve got both tools separated, the real work starts, because offenses rarely need just one of them, and they never need them in only one shape. Heffernan walks through a protection where the short side of the formation gets a tight end nudge and the opposite side gets a running back chip, at the same time, out of the same play — which means you now need a call that communicates both. “So, we’re going to have to call that something different, all right, or we can use two terms,” he says. “It’s up to you, but these are the questions that I think you should be having, the discussions you should be having in the offseason before you need it.”
He pushes the same logic into a lighter protection, too, in case anyone assumes this only matters when you’re already spending six or seven on protection. Take a five-man scheme and put two skill players — a back and a receiver — into the same helping roles. “Everybody’s involved in pass protection,” Heffernan says, and the payoff isn’t just extra help at the point of attack. A receiver stationed to nudge, rather than released outright, is also a faster checkdown option if the play breaks down: “if we do hit a check down, it’s a faster, more explosive target.” Stack that against a linebacker blitz and the math still favors you. “Even if they do bring a backer, at worst, we’re warm. We’re not true blue hot because we’re going to nudge through that defensive end.” A five-man protection with a nudge built in isn’t really a five-man protection anymore — it behaves like something in between, and your tackle should know exactly which version he’s getting.
Why Should Coaches Rep Pass Protection Answers Before Game Week?
None of this works if it lives only in a coordinator’s head, and this is where Heffernan’s talk turns from technique into a challenge to the room. “Make sure you rep it before you need it, all right,” he says. “Your coordinator might not ever ask. So that part of your job is to go in and say, hey, if we want our tight end to nudge out here, what do we call that? All right, it’s jet nudge or jet rib or jet whatever, okay.” The name doesn’t matter. That it exists before someone asks for it does.
Heffernan is direct about what happens to a staff that skips this work, and it’s a scenario every O-line coach in the room has lived through in some form. “There’s a guy in your conference, some of you might be thinking about him right now, that’s going to be hard as hell to block that guy,” he says. “And if you go through spring, you don’t rep it. You go through training camp, you don’t rep it. The coordinator comes down the hall and says, holy smokes, we’re going to have a hard time blocking this dude. We better have a plan for him.” His answer to that moment is blunt: “Well, shoot, you should have had a plan for him in the off season.” The cost of skipping the work isn’t abstract — it shows up specifically on a Wednesday in October, with a name on the schedule and no time left to build anything real. “You better have a plan for him in your terminology that your kids are familiar with to where it’s not Wednesday or third down day for you guys and you’re going out there… trying to rep something to stop a really good player… that you should have repped already.”
That’s the piece that turns two technique tools into a system: the guarantee and the gravy only help you if the words for them already live in your players’ heads before the week you need them. A tackle can’t set true against a chip he’s never been coached to distrust, any more than he can lean on a nudge nobody ever named. Heffernan’s closing challenge to the room makes the scope of this clear — he wants staffs asking these questions about every personnel grouping, not just the obvious ones: “What if we got an empty and we put double nudges? What would we call that? Have it built, have it built, have the kids understand. Maybe they haven’t heard in a month, but they know that term means that.”
Why Does the Difference Between a Chip and a Nudge Matter for Offensive Tackles?
It would be easy to read this as two separate lessons — one about alignment, one about terminology discipline — but they’re the same idea told twice. Heffernan’s entire framework rests on making sure a tackle knows, before the ball is snapped, exactly what kind of help he’s getting and what it’s worth. The free help from an inline tight end changes the picture before contact. The guaranteed help from a nudge changes how the tackle sets. The conditional help from a chip changes nothing about how the tackle sets — and that, specifically, is the point most rooms get backwards, because “we’ve got him chipping” sounds like a plan when it’s really a maybe.
Off-season installation is what makes any of that usable. A tackle who’s heard “set true, the chip’s a bonus” for the first time in a Wednesday walkthrough during game week hasn’t been taught anything — he’s been handed a new rule under the worst possible conditions to learn one. The terminology has to be old news by the time it matters, worn in enough that “jet nudge” or “double nudge” means something specific and automatic, the way any well-drilled call should. Build the vocabulary in the spring, when nobody’s panicking, and by the time your coordinator does walk down the hall about a genuinely hard rusher, you’re not inventing an answer. You’re just calling one.
How Can Coaches Start Adding Chips and Nudges to Pass Protection This Week?
You don’t need a whole install to start using this. Pick one protection you already run and ask the question Heffernan asks his own room: does the help in this call come from a guy with a protection responsibility, or a guy without one? If it’s a tight end or a receiver with no other job, name it a nudge, and coach your tackle to set with that guarantee in mind. If it’s a back who still owns a blitzer, name it a chip, and make sure your tackle understands that help is gravy, not a plan — he sets true regardless.
Then go build the one call you don’t have yet: the combo, where one side of your line gets a nudge and the other gets a chip on the same snap. That’s the exact gap Heffernan flags — most rooms have named one or the other, almost nobody’s built the call for both at once. Naming it this month, while nothing’s on fire, is the whole difference between having an answer in October and inventing one.
FAQ
What’s the difference between a “chip” and a “nudge” in pass protection, according to Terry Heffernan? Heffernan draws the line at protection responsibility. A nudge comes from a player — typically a tight end or receiver — who has no assignment in the protection count, which makes it guaranteed help: it happens every time the call is made, so the tackle can set knowing it’s coming. A chip comes from a player, typically a running back, who still owns a protection responsibility, usually against a blitzing linebacker. If that blitz comes, the back has to honor it first, which means the chip is conditional — Heffernan calls it “extra gravy” — and the tackle has to set true, as if the help isn’t guaranteed at all.
Why does Heffernan say a six-man drop-back protection with no help sets your group up for failure? His argument is that relying exclusively on a straight drop-back protection — five linemen and a quarterback, with no chips, nudges, or alignment-based help built in — hands the pass rush every advantage of space and time with nothing to slow it down. Without any tools to tighten alignments or add helpers, an offense has no way to adjust when it runs into a rusher its tackle genuinely struggles to handle one-on-one.
What is an inline tight end release, and how does it help pass protection without adding a protector? It’s simply aligning the tight end on the line of scrimmage in a pass concept rather than splitting him out wide. Doing so tightens the defensive end’s alignment before the snap, shrinking the space and time he has to work with. Heffernan uses this as a free form of help — it benefits the tackle “without taking another protector out, without chipping, without nudging,” because it changes the picture through formation rather than assignment.
Why does Heffernan insist on building protection terminology before the season instead of when a tough matchup comes up? Because by the time a coordinator identifies a difficult pass rusher on the schedule, there’s no time left to properly install and rep new calls — it becomes a rushed Wednesday fix instead of a drilled, trusted answer. Heffernan’s rule is to have the vocabulary for every combination of help — nudges, chips, and combinations of both across the formation, even down to five-man protections with “double nudges” — built and repped in spring and training camp, so the answer already exists in the players’ vocabulary whenever it’s needed.
Can a five-man protection include chip or nudge help, or is that only for six- and seven-man protections? Heffernan argues it applies just as much to lighter protections. By aligning two skill players — a running back and a receiver — in helping roles within a five-man scheme, an offense can get “double nudges” without spending extra protectors, while also keeping a fast, explosive checkdown option available if the play breaks down. Even against an added blitzer, he considers the tackle “warm” rather than fully exposed, because the defensive end is still getting touched on the way past.
