6. Genetics
Scotland is one of the most consistent teams in world soccer. They’re almost always awful. One of their worst periods in recent history was under manager Gordon Strachan. They failed to qualify for the 2018 World Cup after a series of performances. Then Strachan raised eyebrows with one of the dumbest excuses in the history of sports. He claimed that Scottish people had weaker genetics than other nations.

The coach said that only Spain had smaller players than Scotland in Europe. We’re talking about the same Spain who won the previous World Cup and European Championships. In sum, this argument just doesn’t hold up. Pseudoscience doesn’t hide the fact that his leadership and tactics were shambolic. Finally, he departed after losing the support of his nation.
