Value, need and opportunity cost in judging a signing

Three questions that get merged

The first question asks how good the competitor is, which is an assessment of ability independent of where they might go. The second asks whether that ability addresses a genuine gap, which depends entirely on the squad already assembled and the way it plays. The third asks what else could have been done with the same resources, which is the question that determines whether the decision was sound.

Public discussion concentrates almost entirely on the first, because it is the only one that can be argued about without knowing the internal position. Collapsing the three produces arguments in which one side is discussing ability and the other is discussing allocation.

Fit as a structural property

A competitor suited to one system can be poorly suited to another, and the difference has nothing to do with the level of ability. Fit depends on the tactical requirements of the role, the attributes of the competitors alongside, and the demands of the competition being played. A side that changes approach after recruiting can convert a good fit into a poor one without anybody involved performing worse.

Because tactical direction changes more often than contracts do, fit is less stable than it appears at the moment of agreement. Assessing fit retrospectively therefore risks blaming a recruitment decision for a subsequent change in plan.

Opportunity cost and the alternatives

Every commitment removes resources that could have been used elsewhere, and the correct comparison is against the best available alternative rather than against nothing. That alternative includes not recruiting at all, promoting from within, or addressing a different position with the same resources. Public assessment rarely constructs the alternative, which makes it impossible to judge whether the chosen option was the best one available.

The alternatives are also partly unobservable, since a side cannot know what it would have achieved on a path it did not take. Acknowledging that limit is more useful than pretending the counterfactual is known.

Squad structure and marginal value

The value of an addition depends on what already exists, because strengthening an area already covered produces less benefit than addressing a weakness. A very good competitor added to a position of existing strength can therefore be a poor decision despite being an excellent acquisition in isolation. Squad limits make this sharper, since registration rules mean an addition can force out somebody who would otherwise have contributed.

Age profile matters too, because a squad concentrated in one age band faces a simultaneous decline that a balanced one avoids. These structural considerations rarely feature in assessment and frequently drive the decisions being assessed.

A framework that survives hindsight

Assessing quality, fit and alternatives separately produces a verdict that remains coherent even when the outcome was unexpected. It allows a decision to be described as sound with a poor result, which is the correct description in a substantial number of cases. It also identifies decisions that were unsound and happened to work, which are the ones most likely to be repeated with worse consequences.

Public discussion has little appetite for that distinction because it removes the satisfaction of a simple verdict. Any ranking of recruitment decisions that ignores it is ranking outcomes and should describe itself that way. Naming the target of the ranking is a small editorial act that quietly removes the largest source of disagreement about its conclusions.
