Murphy, 26, said the players are taking full responsibility for the side's recent drop in form, and are collectively determined to atone in the remaining two home-and-away matches.
"Our playing group takes a fair bit of ownership," he said on Wednesday.
"We set a really high standard for ourselves and we're as disappointed as anyone when we don't get the points.
"Obviously after a loss, like the one up in Brisbane, there's a mourning process you go through and you get over it and start afresh and get another chance six days later."
However, Murphy said "no one is panicking" at Whitten Oval just yet, as they prefer to focus on the year as a whole rather than just the past month and a half.
"The momentum that you guys perceive we've lost over the past few weeks, I tend to look at it in a bigger picture," he said.
"For nine months of the whole season we've really built up a strong belief over the group, compared to what we served up last year.
"In the big picture, we've virtually got a full list to pick from at finals time so we'll get over these next two weeks and get into it."
Murphy said the Dogs have identified finishing the season well as "crucial", and believes the possible inclusion of veteran Scott West in the senior side in coming weeks will decidedly lift morale.
"When you include someone like Scotty West into the side, it would give any team a boost," he said.
"We'd be rapt to have him back and it looks like we won't have to wait too much longer."
The goalkicker said the club's fans can look forward to an exciting and enthusiastic display by his side this Friday night when the Dogs take on the depleted Bombers at Telstra Dome.
"I think you can expect to see a pretty fast and attacking style of footy," he said.
"Essendon always come up and we've had some great battles in my time between the Dogs and the Bombers, and Friday night footy – apart from finals, it's why you play.
"I think you can expect a good show."
