THEY have seen their worst - and their best - all in the same game.

They have pulled apart all that makes the difference between falling 50 points behind Carlton in the first half at the MCG on Easter Sunday - and a nine-goal second half that takes Port Adelaide to within three points of a miraculous win.

Now the Port Adelaide coaches and players are working to put the answers into a much-needed win against 16th-ranked West Coast at Adelaide Oval on Saturday afternoon in the AFL's Anzac Round.

"They've seen it; they've understood it - now they have to 'do' it," Port Adelaide senior coach Ken Hinkley said on Friday of the week of intense review and reconditioning at Alberton.

"In a game like that (against Carlton), (the best and worst) were so close together it is hard not to see (what makes the difference). You saw what we were capable of  - but you also saw what we did in the first half.

"And now it is 100 per cent about the doing ... we can't do any more (analysis). It is now about taking the next opportunity."  

Port Adelaide's midfield was very much working through solutions under the watch of midfield coaches Brett Montgomery and Luke Kelly before the captain's run at Adelaide Oval on Friday morning.

This would appear a clear response to the issues presented at stoppage against Carlton that in the first half beat Port Adelaide at turnovers (scoring 24-2 in the second term) and in scores from clearances (38-20 at half-time and 6-7 in the second half).

"The first half against Carlton set off alarm bells about a lot of our game (not just the midfield)," Hinkley said.

Port Adelaide faces a West Coast unit with its own issues posed by inconsistent form (1-4) and selection problems created by COVID protocols. But West Coast comes to Adelaide Oval with a perfect 5-0 win-loss record against Port Adelaide since 2014.

Port Adelaide captain Tom Jonas has declared: "We will win."

"And I loved that Tom was aggressive in his approach to this week and this round," Hinkley said. "He expects us to win. We always expect to win at Port Adelaide.

"(West Coast's perfect record at Adelaide Oval against Port Adelaide) is one of many numbers we are trying to correct. We start with this game by playing at a level that gives us the best chance to win - against a team that has had its own challenges this year.

"We are getting closer. We are getting people back (from injury). Those who came back last week (All-Australian defender Aliir Aliir and All-Australian forward Robbie Gray) will be better for the run.

"We can only answer (the questions posed by the 0-5 start and 0-5 record against West Coast at home) by a winning result. We need to keep working to get that result. We do that by preparing really well to make sure we get the win."

At selection, Port Adelaide has regained Brownlow Medallist Ollie Wines and wingman Kane Farrell, who returns to the AFL less than a year after a knee reconstruction. They replace wingman Karl Amon and father-son draftee Jackson Mead.

Jonas (knee) and midfielder Zak Butters (illness) also are confirmed starters after health and fitness checks this week.

Amon's fall follows his numbers of 22, 18 and 15 disposals in his past three games and a season total of 1.7.

"Karl would be the first to admit he has not been in his best form," Hinkley said. "He is a really important part of our side - and we need him in really good form. We are trying to support him in getting back to good form. This is why we make these decisions.

"There is a lot to his game. It is not just, 'He is not doing A'. His game as a whole is not where he would like it to be and where we need it to be."

Hinkley acknowledged it "would be unfair to Karl" to suggest the selection agenda has identified Amon as the lone out-of-form player at Alberton.

"We are clearly not all playing great football collectively," Hinkley said. "There are some decisions you can and cannot make (at selection, depending on options from the SANFL). We have taken the opportunity this week to give Karl the chance to get in better form.

"Let's not isolate players (who have been spared the axe at selection). Let's look at the team - collectively, it is not in good form. If the team can work better together, that will help every player be in better form.

"Sometimes you have to do these things - and Karl works really hard, incredibly hard at training. He will do everything he possibly can (to be at his best). He has had an unbelievable two or three years. We just need to see Karl at his best."

Wines returns after missing one match with the heart irregularity that caused nausea and dizziness before half-time of the Thursday night home game against Melbourne. Farrell plays AFL for the first time since round 16 (July 3) last season.

Wines required a medical clearance to return to training this week and, adds Hinkley, "we were never going to take the risk with Ollie".

"It has been ticked off medically by more than one person," Hinkley said. "Ollie will be aware of his condition; so will our medical team. We hope it never happens again - but it is not something we can stand here to say it categorically will not. Because he has had one episode, we are on high alert."

Farrell returned to the SANFL earlier this month, just nine months after injuring his knee.

"It is a significant effort by Kane to get back in only nine and a half months and two games in the SANFL," Hinkley said. "We rate him highly, clearly. That is why we have him back in the AFL team. We were really disappointed when he went down because we thought he was just about to breakthrough as an AFL player. He has some real top-end talent that we like and he is a fantastic person.

"Talk about keeping the mood up? When you tell the players that Kane is coming back, that brings some energy to the group because he is such well-liked player."

Hinkley expects no issue with the crackdown signalled by the AFL on umpire dissent, in particular with "arms out" that leads to a 50-metre penalty.

"Our players are clear," Hinkley said. "The intent of the rule is good. It is there to make sure we respect umpires. The players are learning to get better at that. I get it is an emotional game and it is frustrating at times.

"But the players are clear on what they need to do."

As the AFL celebrates its ANZAC Appeal Round Port Adelaide will be honouring its deep links with the defence force at Adelaide Oval, with an Anzac ceremony honouring those that have served to be held before the first bounce.

The playing group will also be sporting special Anzac Round guernseys, inspired by club legend and national war hero, Bob Quinn. The match-worn guernseys will be auctioned post-game with all proceeds going towards the RSL’s ANZAC Appeal.
