Fremantle coach Ross Lyon is ready to wield the axe and play the kids after the Dockers suffered their second straight big defeat to start 2017.

After losing to Geelong by 42 points at home in round one, Fremantle were walloped by Port Adelaide by 89 points, and currently sit last on the ladder.

Lyon conceded the effort simply wasn't there on Sunday afternoon, and changes will need to be made over the coming weeks.

"We'll have to make some changes on the back of that," Lyon said.

"We just can't keep rolling on with the same personnel.

"We've had some really loyal servants.

"I'm really protective of my players because they give so much, but on these results, we're just going to have to start playing kids."

Dockers young guns Harley Balic, Ethan Hughes, Tommy Sheridan and Griffin Logue will all surely come into contention on the back of Lyon's comments.

"We stuck with the group, showed faith, it didn't get delivered on and so now we need to act," Lyon said.

"There's only so much below.

"We haven't got 20 first-round draft picks sitting there.

"Over the last few weeks Peel (Thunder) have been okay.

"Is Griffin Logue ready? Probably not.

"Harley Balic's finally put three weeks together, so we'll look at him.

"Ethan Hughes (is in the mix), Tommy Sheridan probably could've been in on his form."

With his side 0-2 and facing the challenge of hosting the reigning premiers next weekend, Lyon once again stood up for his players and said he was the man to blame.

"I'm not separating myself from the players, the buck stops with me, I've never shied away from that," he said.

"You take your bouquets and you take your hits, so clearly there's some hits to come and we'll stand up."
