Measuring the unmeasured in football

In the modern era, performance analytics dominate the discourse. Clubs track every sprint, every high-press trigger, and every expected goals contribution with ruthless efficiency. Yet, the tragic death of Sheffield United midfielder Maddy Cusack reveals a profound analytical void in the way teams monitor the internal state of their squads.

The inquest into Cusack's death, which has been adjourned again as of July 2026, forces a necessary re-evaluation of how sports science accounts for non-physical markers. While teams invest millions in biometric tracking, the psychosocial health of the individual remains largely off the radar.

Defining the failure of metrics

Current high-performance departments prioritize physical readiness above all else. In the 2023-24 WSL season, top-flight teams averaged 92 percent availability for matches among their core rotation players. These figures are touted as markers of success, yet they fail to capture the human element underlying the performance.

If we treat athletes solely as sets of data points, we miss the internal decline that precedes physical breakdown. Cusack was a fixture at Sheffield United, a player whose commitment reflected the club's identity. However, when an inquest is delayed repeatedly, it signals that our current frameworks for institutional responsibility are structurally inadequate.

Moving beyond fitness tracking

Clubs frequently cite physical durability as a key performance indicator. The recent reporting on the Maddy Cusack inquest indicates that the legal process is struggling to reconcile the club's environment with the reality of her passing. We must ask why this data is not tracked with the same rigor as heat maps.

Football analytics often ignore the 'human cost' metric, which tracks player turnover not due to injury, but due to internal burnout or emotional attrition. If a club's average player retention rate drops by 14 percent over three seasons, it is not a statistical anomaly. It is a failure of internal management.

We have reached a point where the granular analysis of the sport is at its apex, yet the governance of player welfare remains stuck in the amateur era. The time required for this inquest underlines a systemic hesitance to look inside the locker room. If we can calculate the probability of a goal from 25 yards based on the angle and pressure applied, we can certainly do more to measure the wellbeing of those on the pitch.

Ultimately, the numbers provided by GPS vests and xG models are empty if the club environment does not support the human behind the kit. Until player advocacy is quantified as heavily as passing accuracy, we are missing the most important variable in the entire game.
