Use Your Head

As I type and if I recall correctly, the past four world cup goals have been headers. Wilfried Bonny (Ivory Coast) Gervinho (Ivory Coast) Enner Valencia (Ecuador) (bouncing the ball off the goal line too) Admir Mehmedi (Switzerland) That seems like a rare rund to me. It turns out to be surprisingly hard to find any calculation of what fraction of goals are scored with the head. I finally learned that 21% of league 2 goals are scored with heads (I would have guessed closer to one in ten and no I don't know what league 2 is) So that means that the chance that a series of 4 goals are all headers is about 1/625 which isn't very low (the game has been played for a while).
