At 2-4, last year's grand finalists are under the microscope ahead of a Thursday clash with GWS Giants, the likely loss of concussed ruckman Oscar McInerney only compounding problems.

A one-point loss to Carlton was followed by an away defeat to Fremantle before Collingwood also came from behind to beat the Lions at the Gabba.

They took care of North Melbourne in Adelaide and victory at the MCG last week against Melbourne restored order, before a third setback at their home ground on Saturday.

Fagan said Geelong outsmarted his side in the wet but he doesn't think it's time to panic.

"We created a bit of a fortress for ourselves and right now that's being challenged," he said.

"We've got to stay positive, keep working and I know it'll turn around.

"I don't think there's anything in particular teams are doing to us to make it occur, it's just one of those things in sport.

"We haven't put in any disastrous performances but we've found ways to lose, without taking credit away from our opposition."

He said Carlton, Sydney and the Giants showed last season that it was premature to write off a team after six rounds.

"We exaggerate where teams are on the ladder at this point of time in the year," the coach said.

"Go and have a look at the ladder after 13 games last year."

"Swans and Giants had won five games, Carlton four-and-a-half."

All three finished inside the top-eight while the Giants and Blues went on to play preliminary finals.

"We're 2-4. It doesn't look good, but there's a lot of this season to go and I've got strong belief in our group.

"There's some reasons for it; we have to stay positive and work our way out of it.

"We've got to find a way to win on Thursday, just have to find a way."
