Running backs are a key part of a football team. They must possess a unique combination of speed, agility, vision, and toughness that allows them to excel at rushing the ball, catching passes, and blocking.

Size isn’t often a factor with running backs, as they can be tall or short. However, they must have the same quality of speed, power, and toughness to be effective.

Legendary NFL running backs like Walter Payton, Emmitt Smith, and Barry Sanders demonstrated relentless skill and determination that made them exceptional players at their positions.

The running back is one small piece on the football field, but a great running back can make a major impact.

Running Back In Football

Running back in football

The running back is the focal point of the offensive backfield. Their main role is to carry and run with the football to try to score a touchdown.

However, great running backs are also threats, catching passes and blocking on behalf of the quarterback and other players.

Their versatility, reliability, and work ethic make them indispensable.

Let’s learn more about the primary roles of a running back.

Running with the Ball

Running backs strive to advance the ball by evading defenders. By spotting gaps and cutting across the field, they can gain extra yards after contact. Running plays drive the offense, but running backs also contribute through deception, like faking runs while setting up passes.

Catching Passes

Running backs must catch passes from the quarterback using proper technique.

After securing the ball, they quickly read blocks and defenders to try to gain as much yardage as possible. Using their blockers effectively can help maximize these yards.

Blocking for Teammates

Running backs protect the quarterback and open space by blocking defenders. Shoulder blocks and aggression are key.

Staying close to lead blockers allows them to contribute most effectively here. Skilled pass-blocking running backs like Ezekiel Elliott help power their team’s whole offense.

Types of Running Backs

Halfbacks, tailbacks, and fullbacks have distinct roles that serve the running game. Halfbacks are nimble and often handle rushing plays. Tailbacks can both run and catch. Fullbacks mainly block and protect other backs. Together they allow offenses to operate smoothly.


Halfbacks align close behind the quarterback and tend to control rushing plays. Tailbacks are often identified in split back formations, lining up next to another running back in the backfield.

Here is an example of a halfback.

Tailbacks line up behind the quarterback in a T-shape. They can run, catch passes out of the backfield, and quickly change direction, accelerating through holes.

Tailbacks can often be found lining up directly behind the fullback in the I formation.

Greats like Jim Brown and LaDainian Tomlinson made the most of the tailback’s versatile role.

Here is how you can identify a tailback in football.



Fullbacks are larger backs focused on blocking for the primary halfback. These players used to be relevant in the 90s, but the position has since died out due to teams spreading the football out more.

Fullbacks like Mike Alstott used both size and skill to open holes for their tailbacks.

Here is where the fullback lines up on offense.

Essential Skills for Running Backs

Key running back capabilities like speed, agility, vision, and resilience make them challenging for defenses. Honing these lets them shine amidst high-level competition.

Here is a video that can help you learn what running backs in football and why they are so important.

Speed and Agility

Essential movements like dodging tacklers require running backs to have tremendous speed and agility developed through drills and training routines. Resistance training also builds explosiveness off the line.


By quickly recognizing holes and opportunities, even as plays develop, running backs can systematically advance the ball while avoiding big losses. Sharp vision turns uncertainty into reliable gains.


The intense physicality of the position demands running backs display mental and physical durability. Power exercises and emotional discipline help them perform consistently through any adversity.

Developing as a Running Back

Becoming an elite running back requires comprehensive strength and conditioning programs catered to the position’s specialized demands.

Strength Training

Incorporating squats, deadlifts, and other targeted lifts builds the power running backs require while increasing balance and stability for multi-directional movement.

Endurance Building

Boosting cardiovascular health through long runs, intervals, and plyometrics directly translates to sustaining top speed and agility late into games without fading.

Technique and Drills

Mastering the nuances of receiving handoffs, blocking angles, and route running separates decent runners from truly great ones. Specialized drills ingrain muscle memory.

These are the best ways to play running back.
