Outgoing interim Carlton coach John Barker believes some of the Blues haven’t done enough with the opportunities presented to them by the ailing AFL club’s massive list of unavailable players.

A vastly understrength Blues side with 19 players missing was outscored 15 goals to three in the second half on Saturday by GWS Giants in an 81-point away loss in Sydney.

Barker felt some of those called in weren’t capitalising on their chance.

“They have been given opportunities on the basis of the fact that we’re really struggling for man power,” Berber said after the game.

“If I was in that same situation I’d be taking those opportunities a little bit more strongly than some of these guys have.”

He didn’t want to talk about those players he perceived weren’t doing enough.

“I prefer not to talk about the guys not giving us effort, because they are writing their own destinies at the moment,” Barker said.

“But the guys I want to talk about are the guys that are giving us effort, the guys that we are going to build a team around that are going to take us where we want to go.”

He said that list included Patrick Cripps, Matthew Kreuzer, Sam Docherty, Matthew Dick and Dylan Buckley,.

“They are the guys who are going to take us forward, they are our future,” Barker said.

With newly appointed head coach Brendon Bolton watching at the ground, Barker admitted it was a tough situation for him going into his final match in charge against Hawthorn next week.

“We’re about to lose a couple more in terms of surgery, we all know about ‘Murph’ (captain Marc Murphy),” Barker said.

“Sam Docherty I think is going to go for surgery early in the week and maybe one other.

“The task gets harder and the challenge gets greater.”

He admitted the Blues would be vulnerable against the Hawks, who smashed them by 138 points earlier in the season.
