The angle of pursuit in American football is the path a defender takes to meet a ball carrier. Instead of running at where the runner is now, the defender aims at a point ahead of them, where the runner will be when they arrive. The right angle depends on the defender’s speed compared with the ball carrier’s, how far away they are, and where teammates and the sideline are. A good angle turns a potential long run into a short gain, while a bad one, usually too flat or too shallow, lets the runner outrun the defender and break a big play. Coaches often say that every defender on the field has a pursuit responsibility on every snap.
This guide explains how pursuit angles work, the factors that change them, how each position group pursues, how teams coach pursuit, drills and common mistakes.
How pursuit angles work
Imagine a running back breaking toward the sideline. If a defender runs straight at the runner’s current position, by the time they get there the runner has moved on, and the defender ends up chasing from behind. If the defender instead aims for a spot farther down the field, they can meet the runner at that point. The faster the ball carrier is relative to the defender, the deeper the angle needs to be. The farther away the defender starts, the deeper the angle as well. Getting this right is part geometry and part judgement, learned through practice and film.
Factors that change the angle
| Factor | Effect on the angle |
|---|---|
| Ball carrier’s speed | Faster runners need deeper angles |
| Defender’s speed | Slower defenders must take deeper angles |
| Distance from the ball | The farther away, the deeper the angle |
| Sideline | Acts as an extra defender; angles can be tighter when the runner is near it |
| Teammates’ positions | If another defender is forcing the runner back inside, angles adjust to that help |
| Blockers | Defenders may need to take a path that avoids or beats blockers |
Pursuit by position
Defensive linemen
Linemen play their gap first, then chase. On runs away from them, backside linemen pursue flat down the line of scrimmage to cut off cutback lanes, then turn upfield and chase at a deeper angle if the runner breaks outside.
Linebackers
Linebackers read the play, fill their gaps and then pursue inside-out, keeping the ball carrier on their outside shoulder so the runner cannot cut back behind them. They are often the key tacklers on outside runs.
Defensive backs
Cornerbacks and safeties are often the last line of defence, so their angles must be deep enough to prevent touchdowns. Safeties coming from deep take angles that meet the runner downfield, especially on breakaway runs.
Inside-out pursuit and leverage
A core principle is to pursue inside-out: stay slightly behind the ball carrier’s inside shoulder so they cannot cut back toward the middle of the field. The middle is where most help is, so forcing the runner toward the sideline, where teammates and the sideline itself can trap them, is usually the goal. Defenders who overrun the play by getting ahead of the runner give up cutback lanes.
How teams coach pursuit
- Effort standard: every player runs to the ball on every play.
- Angle landmarks: coaches give players aiming points, such as a yard line or hash mark ahead of the runner.
- Film review: coaches show good and bad angles from game tape.
- Team pursuit drills: the whole defence practises pursuing a ball carrier to different spots on the field.
- Tackling technique: good angles set up safe, effective tackles.
Drills to practise
- Pursuit drill: the defence reacts to a snap and sprints to cones representing the ball carrier’s path on each sideline.
- Angle tackling: a runner goes toward the sideline and the defender takes an angle to make contact.
- Inside-out shuffle: linebackers shuffle and sprint while keeping inside leverage.
- Open-field tackling: defenders break down and tackle in space after taking an angle.
Common mistakes
- Angle too flat: the runner outruns you.
- Overrunning the ball: gives up cutback lanes.
- Loafing on the backside: leaves no help if the runner cuts back.
- Losing inside leverage: lets the runner get to the middle.
- Arriving out of control: leads to missed or unsafe tackles.
Tackling rules and safety standards differ between youth, high school, college and professional football. Follow the NFHS, NCAA, NFL or league rulebook, and teach safe tackling techniques that keep the head out of contact.
Pursuit angles by play type
| Play type | Pursuit focus |
|---|---|
| Outside run (sweep or toss) | Backside defenders take deep angles; playside defenders keep outside leverage and force the runner back inside |
| Inside run | Linebackers fill gaps first, then pursue inside-out to stop cutbacks |
| Screen pass | Defenders recognise the screen early and take angles that beat blockers to the catch point |
| Quarterback scramble | Rushers contain, coverage players keep receivers covered and close on the quarterback at the line of scrimmage |
| Kick return | Coverage players stay in lanes and take angles that keep the returner inside the coverage |
Why pursuit wins games
Teams that pursue well give up fewer explosive plays. A long run or catch-and-run usually happens when one defender misses a tackle and nobody else is in position to help. When every defender runs to the ball with a good angle, a missed tackle becomes a short gain instead of a touchdown. Coaches often grade pursuit on film, counting how many defenders are near the ball at the end of each play. Consistent effort and correct angles are among the most coachable parts of defence, and they separate disciplined defences from average ones.
Pursuit and tackling safety
Good angles also make tackling safer. A defender who arrives under control and at a sensible angle can break down, keep the head up and wrap the ball carrier. A defender who arrives late and flat often lunges or dives, which increases the risk of head contact and missed tackles. Teaching proper angles is part of teaching safe tackling.
Using landmarks and the sideline
Many coaches teach specific landmarks, such as aiming for a yard line five or ten yards ahead of the runner depending on speed. The sideline acts as an extra defender: when the ball carrier is near it, defenders can take slightly tighter angles because the runner has less room to escape outside. Recognising how much field the runner has is a key part of choosing the right angle in real time.
Frequently asked questions
What is a pursuit angle in football?
The path a defender takes to reach the spot where the ball carrier will be, not where they are now.
Why is inside-out pursuit important?
It prevents cutbacks to the middle of the field, where the ball carrier has more room and options.
How do you practise pursuit angles?
Use team pursuit drills, angle tackling drills and film review to learn the right depth for different situations.
