Italy, England & France were ranked 5th, 8th & 9th respectively in the World rankings.
Uruguay, Paraguay, Ghana were ranked 16th, 31st & 32nd.
Your definition of a poor team?. Italy, England & France all ranked in top 10 & eliminated early? or Uruguay, Paraguay & Ghana who went further into the tournament?.
Evidently it shows poor performances through early elimination. The team with the highest distance covered, best passing completion rate, suprise, suprise won the tournament. Team with the best stats won. Teams in general with poor stats dropped out early. Good indication.
Such as Uruguay, Paraguay & Ghana? Yes! If you want to reach the latter stages of the tournament.
Because there yardage outputs & work rates during games fell short of the teams who reached the latter stages.
