Some claim the spine of a football team – positions 1,6,7,9 – is the key to a premiership. Others would argue that forwards, and defence win games.

I would say it’s a combination of all, as well as a special team cohesion which is not shown by the numbers. For example Manly sit on top of the ladder, with the fourth most attacking plays, ninth most metres, and the 10th-best defensive percentage.

This is compared to the Cowboys who sit 12th, with the fifth most attacking plays, third most metres, and the third-best defensive percentage. If it was purely mathematical, Manly would not would not be in such a lofty position.

The purpose of this article is to rank a teams reliance on their spine in attack. My method was to add up all the tries, try assists, line breaks, line break assists, forced drop outs and 40/20s that have been notched by a team’s fullback, five-eighth, halfback and hooker.

I would then divide this figure by the number of games played by the team to receive an overall number. This numbers represents the average number of “attacking plays per game” a spine had produced.

I would then do the same for the entire team to get a total team “attacking plays per game”. I then used these two figures to calculate what percentage of attacking plays the teams spine had performed of the total.

For example the Cowboys relied on their spine for 57.95 per cent of the total attacking plays, while the Roosters only relied on their spine for 41.87 per cent of the total.

The problem with this method is that I have not factored in injuries during the game and swapping of positions, such as the Roosters routinely do with their fullbacks. However this effectively should be minimal as Anthony Minichiello and RTS have only have a difference on three attacking plays, so hopefully it evens out.

The teams are listed below from highest reliance on the spine to lowest. I have also added in a number of other figures, for comparison. Its hard to know if such statistics have any use.

Sometimes, the numbers confirm what you already suspected. For example the Bulldogs’ spine have the 14th most attacking plays, and the team has the 12th most, which is not spectacular for a team coming third. However, they have the most metres by far, and the second best defensive percentage.

These figures seem to confirm that the Bulldogs success belongs to their forward pack and not their spine. However such numbers do not take into account the hooker’s control of the ruck, or the halves direction during play.

Other times, stats make no sense at all. The Cowboys for example tick every statistical box of a top eight team, and yet they sit outside the eight. Perhaps it is over reliance on their spine, or other issues.
