Fremantle coach Mark Harvey has called on his charges to "evolve" and climb "over the mountain" after their 43-point capitulation to St Kilda on Sunday.

Harvey admitted too many of his players sat back and became spectators in the 17.10 (112) to 9.15 (69) loss and that they must learn how to cope with adversity.

"I said to the group I want to see the side evolve when it is not going their way," Harvey said.

"I spoke about climbing over the mountain when it gets a little bit tough to get out of situations, finding out about each other."

After putting in a brave effort against Sydney two weeks ago, the Dockers surrendered meekly to the Saints after halftime, with Harvey left to lament some lazy manning up.

"I thought at times the players were not demanding enough of each other when St Kilda were just kicking the ball around," Harvey said.

"That results in uncontested marks and an easy path to goals.

"As I said to the group after the game, look no further than yourself. Ask yourself what happened and what can be the difference in performance from one week to the next.

"The game is not that difficult from a basic thing like manning up when they have got the ball.

"It takes organisation and concentration.

"At times you are not going to finish up on your direct opponent but it is how you cover for each other.

"We had too many guys sit back and be spectators when that happened."
