With only a handful of 2026-27 Scottish Premiership matches completed, no side has pulled clear in clean sheets, leaving implied probabilities tightly clustered between 46.5% and 49.0%. Early defensive metrics show St Mirren conceding just three goals in four games with three clean sheets, Celtic allowing two in four while keeping two shutouts, and Rangers, Hearts, and Motherwell posting comparable records. Squad changes, including new management at several clubs and key personnel shifts such as Hearts players joining Rangers, have not yet produced sustained defensive edges. Over a full campaign featuring 38 matches per team plus variable fixture difficulty and form fluctuations, these factors sustain competitive balance rather than favoring any single side.
