PORT ADELAIDE coach Mark Williams is confident the Power can dig their way out of the hole they have created after a 0-4 start to the season.

Port Adelaide blitzed the Brisbane Lions in the opening three quarters on Saturday night, but the Power lapsed and squandered what should’ve been a match-winning 47-point lead.

Williams, who like the playing group was visibly shattered after the loss to the Lions, had a more positive outlook on the result on Monday.

"I thought we played fantastically well for three quarters, so we haven't got it all right, but we've got most of it right," he said.

"The most important thing for us is to play four quarters. "We haven't done that once this year. We've been competitive in three games and haven't got any result.

"Competitiveness is the number one thing to get in footy and then after that, obviously, the wins.

"The facts are that no team plays four quarters every week- that's the truth.

"Always in your way is the opposition trying to do something as well. You want to play [an] aggregate of four quarters better than theirs and you'll get a result.

"You just keep working on consistency and focusing on what you're trying to do and understanding young players.

"We're very, very confident we'll get out of this."

Last year, the Power won six out of their opening seven games before dropping the next four.

Williams said his team was still developing and would get better with time.

"It's really important to note that almost every year we've been here [in the AFL] we've strung a lot of games together and we've lost some groups of games together as well, so there is an understanding that 'yeah it does happen to a lot of teams'.

"At the end of the year there will be a lot of teams who've lost 10 games, or maybe nine, and still play finals, so just because you lose them in a row you're mindful that it's not great, but you certainly have a wider view that you're not too far from it."

Williams revealed the coaching staff had spent more than four hours reviewing Saturday night’s disappointing final quarter fade-out but said the club would not make any rash selection decisions based solely on that 30 minutes of footy.

"That [dropping players] always has a little to do with who else is available - that's one thing. Secondly, if you judged our performance on the last quarter most of the players would get dropped and, with some of the things we did [as coaches], we'd drop ourselves too," Williams said.

"The fact is the first three quarters were outstanding and players played very, very well, so we'll judge them on the three quarters rather than the one."

The roles were reversed at Alberton on Monday with Williams stepping up to the plate for the media press conference, which is usually assigned to a player, while the players, and in particular the leadership group, ran training.

Williams said both the playing and coaching groups had taken responsibility for Saturday night’s loss, but he didn’t dismiss suggestions that Port Adelaide and Adelaide, who also lost, suffered last week as a result of the bruising Showdown in round three.

Fremantle and West Coast also experienced defeats in the wake of their western derby the week prior.

"I know a lot of you questioned whether the Showdown last week had something to do with it [the last quarter] and I'm thinking it probably did now," he said.

"Looking back, as I said, I reckon I've seen live or on the TV probably 2000 games of football in my time and I don't think I've ever seen a game, like that one against Brisbane, before."

"So I can't dismiss it [the impact of the Showdown], especially if you link together maybe the Showdown and derby games in WA - there’s probably something in it."
