Aliir Aliir's game-winning spoil was the story of the round, but even with a two-win, two-loss record, Port Adelaide has defensive issues.
The Power has conceded 388 points in four rounds, the third most in the competition behind West Coast and Hawthorn.
For a team that could yet make a run into September, that is concerning.
A lack of size and poor one-on-one defending in the backline have been worrying signs for hot-seat coach Ken Hinkley.
Despite an improved performance against the Swans, captain Tom Jonas (188cm) and Aliir (194cm) have struggled to contain the game's forwards and struggle to match up on the competition's tall forward lines.
Former Sun Trent McKenzie (191cm) has stabilised that backline in two appearances (both wins) but remains a smaller key defender option.
This issue is far from new. Picking up a tall, lock-down defender was a priority for Port Adelaide in the trade period, with the club unlucky to miss out on Geelong's Esava Ratugolea.
So, how can they make it work?
Other defensive options
The question looming over Port Adelaide's season is how they fix this gaping hole in their side now, and in the future.
Tom Clurey (193cm) and McKenzie are the tertiary key defender options for the Power but have both been struggling with form and injury in recent years.
At their best, the duo are solid contributors, but their size still leaves more to be desired if paired with Jonas and Aliir.
Jake Pasini (192cm) is one who could be in line for an AFL stint, with the 22-year-old defender impressing in the pre-season and growing SANFL form.
Pasini was close to a debut in 2022, before rupturing his ACL in the reserves. The Swans Districts player is a strong mark and could play an intercept role alongside Aliir and Jonas.
Dylan Williams, a small defender, impressed in his second AFL game against Sydney and could find himself at home at half-back for much of the season.
Port Adelaide's strange drafting habits
Interestingly, Port's SANFL side is full of height. Ruck stocks are saturated, with Dante Visentini, Sam Hayes, and last year's mid-season draftee Brynn Teakle all developing well.
Forwards, too, are well represented, with Tom Scully, Ollie Lord, and even the axed Mitch Georgiades appearing for the Magpies.
And then the defenders. The Power have left it late in their succession plan, picking up two key defenders in last year's draft in Tom McCallum (193cm) and Kyle Marshall (201cm).
While the duo are two of Port's tallest key defenders, they're still raw with their decision-making and need to build a bigger frame before their AFL debut.
Despite his eye-catching height, Marshall was taken with the final pick of the 2022 NAB AFL Draft and looks to be a long-term project.
Could a position swap be a quick fix?
With an over-population of ruckmen, and the development of lock-down defenders a process just beginning, Port Adelaide is trialling Teakle in defence.
The Western Australian ruckman stands 204cm tall and would be an important inclusion if he can get his defensive craft right — yet, even this option seems unlikely for Port.
Speaking to the media last week, assistant coach Josh Carr dispelled any hopes that Teakle could be a quick fix.
"It's something we're exploring with Brynn and obviously with a need for a tall defender," he said.
"Brynn has still got a bit of work to do to be an AFL defender but we're definitely having a look at that."
