Disaster Index: 5.1 Entry: The Ah But Problem Cause: Scotland winning their opening World Cup fixture in 28 years and immediately identifying reasons to be concerned. Category: Emotional / Structural Evidence: 1-0 win over Haiti. Clean sheet. Three points secured. Domestic dissection of the performance began before the final whistle had fully sounded. The word "nervy" appeared in print before the word "historic." Historical precedent: Scotland's relationship with uncontaminated satisfaction is long-standing and well-documented. No clean data point exists from which to measure its absence. Affected parties: Steve Clarke, the squad, anyone who would like to enjoy a moment for its duration. Immediate outlook: Morocco next. The Ah But problem will not have resolved itself by then. It may, however, have acquired new evidence.
