I'm a way-too-low-scoring sport the correlation between superior play and scoring is too tenuous. There is still a correlation between superior play and scoring of course. That's why Barcelona and Bayern Munich win their league so often over the course of a long season.

But examples of this flaw abound. Portugal winning the European championship this year. Seattle winning the MLS cup last year in a final where they DIDN'T EVEN HAVE ONE SHOT ON GOAL! And Cincinnati FC beating Chicago in penalty kicks in a US open cup game. Upsets are a sometimes healthy result in a healthy Game/sport. But too many is a symptom of a flawed game.
