If you’ve ever watched American football and wondered “is a halfback a running back?” the simple answer is yes. A halfback is indeed a type of running back, but there’s much more to this story. This confusion comes up often because football terminology can be tricky, especially when different terms seem to describe similar positions.
Let’s dive deep into the world of NFL backfield positions and clear up this common question once and for all.
Is a Halfback a Running Back: The Simple Answer:
A halfback is absolutely a running back – they’re just a specific type of running back. Think of it like this: all halfbacks are running backs, but not all running backs are halfbacks. The running back position includes different types of players who line up in the backfield behind the quarterback.
In modern NFL terms, when people say “running back,” they usually mean the halfback – the primary ball carrier who gets most of the handoffs from the quarterback. However, the running back family also includes fullbacks, who have different jobs on the field.
The confusion exists because football terminology has evolved over decades. What we call positions today isn’t exactly the same as what coaches called them 50 years ago. Many fans use these terms without knowing the specific differences, which adds to the mix-up.

Different Types of Running Backs in the NFL

Halfbacks: The Main Ball Carriers
The halfback is usually the star of the backfield. These players are built for speed, agility, and making defenders miss. When you think of famous running backs like Adrian Peterson or Ezekiel Elliott, you’re thinking of halfbacks.
Key responsibilities of halfbacks include:
- Receive handoffs from the quarterback and carry the ball
- Run through holes created by the offensive line
- Catch passes out of the backfield as a receiver
- Line up as a receiver on certain pass plays
- Block for the quarterback on passing situations
Halfbacks are typically smaller and faster than fullbacks. They need to have excellent vision to find running lanes and the speed to break away from defenders. Most halfbacks weigh between 190-230 pounds and can run very fast.
The halfback behind the quarterback gets the majority of running plays in most NFL offenses. They’re expected to gain yardage on first down, break tackles in the open field, and be reliable when the team needs to run the football.
Fullbacks: The Lead Blockers
Fullbacks are the bigger, stronger cousins of halfbacks. While halfbacks focus on carrying the ball, fullbacks are primarily used as a lead blocker for other running backs. The fullback will often attempt to clear a path by blocking linebackers or safeties who try to reach the ball carrier.
Modern fullback responsibilities:
- Act as a blocker for halfbacks on running plays
- Protect the quarterback on pass plays
- Catch short passes as a receiver on short routes
- Handle short-yardage situations and goal line back duties
- Block defensive players trying to tackle the primary runner
Fullbacks are usually bigger than halfbacks, often weighing 240-260 pounds. They’re built more for power than speed. In today’s NFL, many teams don’t use fullbacks regularly, preferring to put more receivers on the field instead.
The position has changed dramatically throughout NFL history. In older offensive formations like the I-formation, the fullback played behind the quarterback but in front of the halfback, creating a straight line in the backfield.
How NFL Teams Use Different Running Back Types

Traditional Backfield Formation
In classic football formations, teams would line up with both a fullback and halfback in the backfield. The fullback lined up closer to the line of scrimmage, while the halfback lined up deeper, behind the fullback.
This offensive formation allowed teams to run powerful ground attacks. The fullback could lead block on running plays, while the halfback followed behind with good blocking from the offensive line. This setup was especially effective for short yardage situations and when teams wanted to control the clock.
Modern NFL Backfield Evolution
Today’s NFL looks very different. Most offensive coordinators prefer using one or two running backs at most, and they often skip the fullback entirely. Instead of the traditional I-formation, teams use more spread formations that put multiple receivers on the field.
Why this change happened:
- Passing game became more important
- Defenses got faster and more athletic
- Teams want more versatility from their players
- Salary cap makes specialists expensive
Modern running backs need to be complete players. They must run the ball effectively, catch the ball out of the backfield, and block for their quarterback. This versatility makes them more valuable than players who can only do one job well.
Comparing Running Back Types
Position | Primary Role | Size Range | Key Skills |
---|---|---|---|
Halfback | Ball carrier | 190-230 lbs | Speed, vision, receiving |
Fullback | Lead blocker | 240-260 lbs | Blocking, power, short yardage |
Tailback | Same as halfback | 190-230 lbs | Same as halfback |
Special Situations and Running Back Usage

Short-Yardage and Goal Line Situations
When NFL teams need just a few yards for a first down or touchdown, they often change their approach. Some teams bring in power backs – bigger, stronger running backs who can push through defenders near the goal line. Others use their regular halfback but add extra blockers like a tight end or even offensive linemen.
The running back’s success in these situations often depends on the offensive line creating holes and the runner’s ability to push through contact. Teams might also use different formations to confuse the defense about where the ball is going.
Passing Game Involvement
Modern halfbacks are expected to be threats in the passing game too. They run routes like a wide receiver, catch passes in the flat, and serve as safety valves when the quarterback is under pressure. This dual-threat ability makes them harder for defenses to plan against.
When a halfback lines up as a receiver, it creates mismatches. Linebackers might be too slow to cover them, while defensive backs might be too small to tackle them effectively. This versatility is why coaches value running backs who can both run and catch passes.
The Evolution from College to Professional Football
High School Football vs NFL
The running back position looks different at various levels of football. In high school football, teams often use simpler formations and rely heavily on their best athlete to carry the ball. The term tailback is common at this level, though it means the same thing as halfback.
As players move up to college and then professional football, the position becomes more specialized. Canadian football uses similar positions but with some rule differences that affect how running backs are used.
Training and Development
Running backs need specific skills that take years to develop:
Physical Requirements:
- Speed to outrun defenders
- Power to break tackles
- Hands to catch passes reliably
- Vision to find running lanes
Mental Requirements:
- Learning complex playbooks
- Reading defensive alignments
- Knowing when to cut or continue straight
- Pass protection responsibilities
The best running backs in NFL history combined all these skills. They could run between the tackles, bounce runs outside, catch passes, and protect their quarterback when needed.
Modern NFL Trends and Future Outlook
How Teams Use Running Backs Today
Today’s NFL teams are creative with how they use running backs. Some teams use a “committee approach” with multiple running backs who have different strengths. Others rely on one feature back who handles most of the workload.
Popular modern strategies include:
- Using scat backs (small, fast runners) on third downs
- Employing power backs for short yardage
- Having elusive running backs who specialize in making defenders miss
- Using running backs as slot receivers
The Impact of Rule Changes
NFL rule changes have affected how teams use running backs. Rules that favor passing have made the position somewhat less important than it was in previous decades. However, good running backs are still valuable because they can control games and keep opposing offenses off the field.
Teams still need to run the football effectively to have balanced offenses. Defenses that don’t respect the running game can be exploited by teams with good running backs and offensive lines.
Conclusion
So, is a halfback a running back? Yes! A halfback is the most common type of running back in the NFL. When people say “running back,” they usually mean halfback – the player who carries the ball most often.
The confusion comes from old football terms that changed over time. Whether you call them halfbacks, tailbacks, or running backs, they do the same job: run the ball, catch passes, and help move the team forward.
Having a good running back is still very important for football teams. These players need many different skills to succeed in today’s game.
Remember: halfbacks are not just running backs – they’re the most important type of running back in modern football.
