Saints forward Jack Billings is having a career-worst goal kicking season and his side has the poorest conversion rate of any side in the competition in 2018.

Prior to Sunday's game, Billings converted -22 percent of his shots this season, the worst of his career, having scored 4.11 through six games. The left-footer did not score at all against the Demons.

These are statistics based off AFL.com.au's goalkick rating, which considers where a player's shots are taken from, what type of kicks they are and how much pressure the player was under.

He has been poor from snaps at goal too, where he has converted just eight out of 36 attempts throughout his career.

Justin Wenke, Billings' former TAC Cup coach at Oakleigh Chargers, told AFL.com.au that he did not think it was an issue during his junior days.

"As a junior, from my perspective coaching him, he didn't show any of that, anything that he's showing now around goal," Wenke said.

"He's actually a really nice player on the run kicking goals. That's probably what I remember of him."

Wenke backed the former pick three in to regain his touch around goals.

"He's one of those ripping kids you coach that are highly talented and highly motivated. I'd be pretty confident he'll get it right," Wenke said.

"He's wired that way.

"He's such a competitive kid. I hope he gets it right, sooner rather than later I suppose, for St Kilda's sake."

The Saints must resolve their goal kicking woes to draw some positives out of this season, because as we know, bad kicking is bad football.
