The fundamental difference between the National Football League (NFL) and professional soccer lies in the legality of physical contact, where the NFL permits high-impact collisions as a core mechanic of the game while soccer strictly regulates body contact under the Laws of the Game. In the NFL, blocking and tackling are essential tactical requirements, whereas soccer officials frequently penalize pushes or shoves—such as those involving high-profile strikers like Erling Haaland—as fouls that can lead to disallowed goals.
The Mechanics of Legal Contact: NFL vs. Soccer
In the NFL, the game is designed around the concept of “controlled aggression.” According to the NFL Rulebook, players are permitted to use their bodies to block opponents to create lanes for the ball carrier or to tackle the opponent to stop forward progress. While there are strict rules against “unnecessary roughness” or “targeting” the head and neck area, the act of pushing an opponent out of a specific path is a standard, legal play.


Soccer operates under a different philosophy. The International Football Association Board (IFAB), which oversees the Laws of the Game, defines a foul as an offense committed by a player against an opponent if they challenge them in a manner that is careless, reckless, or uses excessive force. This includes pushing an opponent, which is explicitly listed as a foul. When a player like Manchester City’s Erling Haaland uses his physical frame to shield the ball, it is often a fine line between a legal “shield” and an illegal “push.”
For a global audience, it is helpful to understand that soccer refers to “contact” as something that happens during the play, whereas the NFL views “contact” as the primary objective of the play. In soccer, a push that impedes an opponent’s movement is a violation; in the NFL, that same movement is often the goal of the offensive line.
Why Erling Haaland’s Physicality Sparks Debate
Erling Haaland has become a focal point for discussions regarding physicality in the Premier League due to his size and strength. In several match instances, goals have been scrutinized or overturned because Haaland’s efforts to maintain position were interpreted by referees as pushing the defender.
Under IFAB rules, if a player pushes an opponent to gain an advantage, the referee is instructed to award a direct free kick. When this occurs in the buildup to a goal, the goal is disallowed. This creates a stark contrast for viewers accustomed to American football, where a player of Haaland’s stature would be expected to move a defender out of the way to reach the end zone.
The tension arises from the “subjectivity of force.” A referee must decide if Haaland’s contact was a natural part of a shoulder-to-shoulder challenge—which is legal—or a deliberate push to displace the defender. In the NFL, the distinction is simpler: as long as the contact doesn’t involve a prohibited strike (like a punch or a helmet-to-head hit), the physicality is generally encouraged.
The Role of Equipment in Defining Violence
The difference in rules is not arbitrary; it is tied directly to the equipment used in each sport. NFL players wear hard plastic helmets, shoulder pads, and thigh pads designed specifically to absorb the impact of high-velocity collisions. This equipment allows the league to permit “collision sports” dynamics without the same level of immediate risk associated with unpadded contact.
Soccer players wear minimal protection—primarily shin guards. Because the head and torso are exposed, the rules against pushing and charging are designed to prevent injuries. A “legal” hit in the NFL would be catastrophic in a soccer match, which is why officials are quick to whistle for fouls that might seem negligible to a football fan.
Tactical Implications of Contact Rules
These contrasting rules lead to entirely different tactical approaches:

- NFL: Teams employ “power running” games where the goal is to physically overpower the defender. The “bull rush” by a defensive lineman is a celebrated tactic.
- Soccer: Players use “body positioning” and “low center of gravity” to maintain possession. The goal is to outmaneuver the opponent rather than move them physically.
When American viewers watch soccer, they often perceive the game as “soft” because of the frequent fouls. Conversely, soccer fans may view the NFL as overly violent. In reality, both sports are optimized for their specific objectives: one for territory and physical dominance, the other for agility and precision.
Comparative Summary of Physicality
| Feature | NFL (American Football) | Soccer (Association Football) |
|---|---|---|
| Primary Goal of Contact | Stop the opponent or clear a path | Protect the ball or win possession |
| Pushing/Shoving | Legal (within blocking rules) | Illegal (Direct Free Kick) |
| Protective Gear | Full pads and helmets | Shin guards only |
| Referee Focus | Illegal hits/Targeting | Careless/Reckless challenges |
The next major checkpoint for these discussions will be the continuing evolution of VAR (Video Assistant Referee) in soccer, which has increased the frequency of goals being disallowed for subtle pushes. As the Premier League continues to refine how it handles physical strikers, the debate over “manly” play versus rule adherence will likely persist.
