Where is possession most one-sided?

Average distance from an even split. Possession itself averages fifty everywhere — both sides add to a hundred — so the question worth asking is how far apart the two teams end up.

Primera División Femenina (Spain) is the most lopsided: on average a side finishes 12.6 points away from half the ball.
