As VAR technology continues to evolve in professional football, critics and experts are questioning its growing influence and the potential for 'mission creep' in refereeing decisions.

The video assistant referee (VAR) system remains a focal point of debate in professional football as the new domestic season progresses. Originally intended to assist referees in reducing human error, the technology has expanded its scope over the last decade. Experts and fan groups are now questioning whether VAR has moved beyond its intended supporting role to become an overly dominant, game-altering force.

Technological expansion and mission creep

Susmit Gulavani, an assistant professor in AI and machine learning in sport at the University of South Carolina, notes that the introduction of tools like Semi-Automated Offside Technology (SAOT) has increased the precision of certain calls. However, this has created an expectation for perfect outcomes in all scenarios, including subjective ones like fouls or handballs that require human interpretation. This phenomenon, described as 'mission creep,' often leads to game delays and fan confusion. In Germany, the role of VAR has recently expanded to include second yellow cards and corner kicks in the Bundesliga. This shift faced opposition from organized fan groups, who launched a campaign in August calling for the removal of the technology, arguing it diminishes the joy of the sport.

Future of officiating and alternative systems

While a return to football without technology is considered unlikely, there is ongoing discussion regarding how to better integrate it. During last year's U20 men's football World Cup, authorities trialed 'Football Video Support' (FVS), a system allowing coaches to request reviews, similar to challenges in the NFL. While FVS is being explored as a potentially more cost-effective alternative to the current VAR model, experts emphasize that technology should serve as decision support rather than a replacement for human judgment. Jochen Drees, head of VAR operations in Germany, advocates for refining the existing technology rather than removing it. Experts suggest that while AI excels at processing large amounts of data, it lacks the ability to understand the nuance and context required for many sporting decisions.
