Disaster Index: 3.4 Entry: The Hendry Condition Cause: Scotland's heat acclimatisation strategy resting meaningfully on the prior experience of one defender who has been playing in Saudi Arabia. Category: Structural Evidence: Miami humidity classified as unfamiliar to most of the squad. Jack Hendry's Al-Ettifaq posting constitutes the group's primary experiential reference point. A squad's environmental preparation is not usually this individual. Historical precedent: Scotland have historically been calibrated for horizontal rain and a following wind. Heat as a neutral condition has not featured prominently in the tournament record. Affected parties: Outfield players without Gulf-contract acclimatisation; any tactical system reliant on sustained pressing in humidity. Immediate outlook: Hendry's experience is genuinely useful. The Index notes, however, that useful is not the same as sufficient.
