Disaster Index: 2.1 Entry: Precocity Premium Cause: A sixteen-year-old called up to the Scotland Under-21 squad, arriving ahead of schedule into a system that has historically struggled to schedule development without distorting it. Category: Structural Evidence: Kyle Glasgow is 16. Tony Docherty's first U21 squad. The name alone will attract a category of attention the player has not yet had time to earn or refuse. Scotland's pipeline has produced early selections before; the conversion rate into senior tournament footballers remains a matter for the archive. Historical precedent: Numerous. The distance between early U21 recognition and senior tournament contribution has proved longer than it looks from the announcement. Affected parties: Kyle Glasgow; the Scotland development pipeline; anyone who writes the word "starlet" before the player has kicked a ball at this level. Immediate outlook: No immediate risk to senior campaign. The Index records the structural pattern: Scotland selects young with hope and occasionally with care. Which this is has not yet been established. Filed: 16 September 2026 / Under-21 squad announcement
