Recurrent scores in drawn matches

At Rogers Results, there is a short site on drawn games in the V/AFL.

Since I was given a table of all matches won with fewer goals, I have wanted to look at how many of the 143 drawn scorelines are actually unique, which I have done at home with matches won with fewer goals.

A scoreline can be deemed to be unique if and only if each team’s goals, behinds and points is not replicated immediately or by simply swapping the home and away teams. If the scores are equal, the number of goals and behinds by each team or after swapping home and away teams must be the same for a scoreline not to be unique.

In the 143 drawn games, the following set of scores has recurred on four occasions:

That leaves a total of eighty-nine drawn scores that are unique and have occurred only once.

Of these eighty-nine scores:
  • forty-six had the same number of goals and behinds by both sides
  • forty-six had one fewer goal and six more behinds by one side
  • five (two in 1914, one each in 1966, 1968 and 1995) had two fewer goals by one side
  • two (in 1935 and 1948) had three fewer goals by one side (Essendon against Melbourne; Carlton against Footscray)
This confirms to the general pattern of goals score in drawn games. The difference is goals between two sides drawing a game is 0 or 1 with very nearly equal frequency, whilst the nine matches drawn where the difference in goals scored was greater than one stand as very major scoring oddities.
