Australian Football Hall of Famer Terry Wallace has revealed an amazing statistic that underlines Hawthorn’s watertight defence.

The Hawks have ignited their finals chances with three straight wins conceding on average just 59 points in each of those victories.

“Hawthorn has only been scored against five times of the last 173 chains from defensive 50. Five of 173,” Wallace told SEN Drive.

“You get the ball in your back half and try to get it out against Hawthorn, you only score five times in 173 opportunities.

“When the ball is in the back half of the ground, you just don’t get a score out of playing against Hawthorn.”

Hawthorn take on free-scoring Brisbane in Launceston on Saturday and Wallace is fascinated to see how the match unfolds.

“It’s unbelievable how tight their structures are and that’s why it’s going to be interesting,” he added.

“Brisbane take sides on, Hawthorn shut them down. How that plays out on Saturday will be absolutely brilliant.”

Hawthorn go in search of a fourth straight win against the Lions.
