Disaster Index: 3.1 Entry: The Clarke Unknowns Cause: Scotland entering a World Cup managed by a figure whose methods are understood by those close to him and by almost nobody else. Category: Tactical Evidence: A profile of the manager published on the day of the tournament reveals that those who know Clarke best find him difficult to summarise. Clarity of method has not translated into clarity of record at tournament level. The country is proceeding on professional trust. Historical precedent: Scotland have not managed a World Cup group stage since 1998. The comparative data set for Clarke at this level is empty. Affected parties: Scotland squad; tactical planning functions; the segment of support that has been told to believe without a demonstrable basis for belief. Immediate outlook: Index is low. The concern is not that Clarke is incapable. It is that capability at this level remains undemonstrated. The file stays open.
