I think it’s interesting to divide his reign so far into 2 distinct parts. The first is up to and including Euro 2020. The team he inherited was a shambles and completely shorn of confidence. We suffered some heavy losses (Belgium, Russia) but slowly became harder to beat, and gradually picked up enough form to qualify (via the back door) with encouraging performances versus Serbia and England. Win ratio was 41% but with no landmark wins over 90 minutes. Fair to say jury was still probably out at this stage but with some signs that things were moving in the right direction.
Second part is post Euro 2020. Some iconic wins vs Denmark, Spain, Norway. Promoted to the top tier of the Nations League. Best performance in a World Cup qualifying group in many a year but followed by an admittedly disappointing loss to Ukraine in the playoff (and yes to Ireland immediately after during the same dip). And now the best start to a qualifying group in many years with 3 straight wins. Win ratio of 60%. A team that never knows when it’s beaten. A team that scores more goals and has more shots per game than any Scotland team in living memory.
Overall, a pretty decent report card.
