USA Card Harshness

Card Harshness

United States

Moderate

What we see

United States is shown a card about every 7 fouls. The teams United States faced were carded about every 10 fouls.

The other side

When those same opponents played United States, they were carded about every 6 fouls.

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.
