SCORING hasn't been lower in the first two rounds for nearly 50 years, with the lowest average total points per game recorded in the opening two rounds since 1967.

The average points per game figure has been 168, three more than that recorded in 1967.

Twice teams have failed to score in a quarter already this season, while 10 times in the first 144 quarters a team has gone  without a goal.

It hasn't stopped the football from being exciting however, with ball movement improving and one third of the games decided by two goals or less.

There have also been 30 quarters where one team has scored five goals or more.

However the figures are an indication that the defensive dominance that coaches know is necessary to win premierships is showing no signs of abating.

Last year's runner-up, the Sydney Swans, have conceded just three points in the final quarter in the first two rounds and only 104 points in the first two rounds.

On the flipside Carlton and Collingwood have already failed to score a goal in one quarter of each of their first two games.

Port Adelaide, Swans' round two opponent, recorded its lowest score since Ken Hinkley took over as coach on the weekend, with the Swans defending the back half of the ground brilliantly.

"It's the biggest zapper of confidence you can get when you continually push it into your forward 50 and you don't hit the scoreboard," Hinkley said.

"I'm a big believer that you have to continue to get score going a bit to keep growing the other parts of your game because once that dries up you feel like everything else is so hard to do."

After averaging 100 points per game in 2014 Port Adelaide is the lowest scoring team in the competition in 2015, although it has faced two of the best defensive teams in the first two rounds in Fremantle and the Swans.

History shows that the premiership team is generally a club that sits in the top four for least points conceded.
