Switzerland Card Harshness

Card Harshness

Switzerland

Limited

What we see

Switzerland is shown a card about every 12 fouls. The teams Switzerland faced were carded about every 7 fouls.

The other side

When those same opponents played Switzerland, they were carded about every 7 fouls. That is close to their own usual rate, so the gap is mostly on Switzerland's side.

What this does not mean

This does not show whether comparable fouls were treated differently. We cannot see how bad each foul was, so a harsher rate can simply mean more bookable fouls. There are not many matches yet, so the number may still move a lot. Here the team is actually carded less than the teams it faced, not more.
