Disaster Index: 5.1 Entry: The Midfield Arithmetic Problem Cause: Scotland's midfield configuration for the Haiti opener unresolved at the point of public discussion, with selection ambiguity entering the record as a categorisable condition. Category: Tactical Evidence: The question of whether Scotland deploy a creative curveball in midfield or proceed conventionally has reached the BBC Scotland level of public deliberation. Steve Clarke has options. The fact that the options require a published taxonomy is itself a finding. Scotland have historically managed selection uncertainty in the direction of the familiar. Historical precedent: The 1998 France World Cup opener saw Scotland approach the Bragan match with defensive pragmatism that foreclosed tactical upside. The pattern of choosing safety over surprise at the moment of commitment is documented. Affected parties: The midfield candidates in question; supporters who have already decided which formation is correct; Steve Clarke. Immediate outlook: A curveball that lands is not a disaster. A curveball that doesn't is a cause. The Index records the condition, not the result. Filed: 13 June 2026 / Pre-Haiti, group stage
