The Dockers dropped a bombshell on Tuesday when they sacked Lyon as coach and Steve Rosich as chief executive.

Lyon still had a year to run on his contract and is set to receive a payment in excess of $600,000 from the Dockers next year if he fails to - or chooses against - joining a rival club in 2020.

Cameron still has a year to run on his GWS coaching contract, while Essendon's Worsfold is also contracted for next year.

But both coaches are under pressure after inconsistent seasons.

The sixth-placed Giants (12-9) have copped thrashings from Hawthorn (56 points) and the Bulldogs (61) over the past fortnight and are running out of time to snare a premiership from their talent-laden list.

Worsfold has been under huge pressure all season but that eased somewhat after last week's 32-point win over Fremantle that secured their finals berth.

Brown, who played 256 games for Brisbane during a decorated career, rates Lyon as one of the top three AFL coaches, and believes Fremantle were wrong to sack him.

Lyon hasn't publicly declared whether he wants to coach next year but Brown feels like the 52-year-old would be a good fit at GWS.

"I would be nervous if I was Leon Cameron coaching GWS," Brown told Nova 100 radio.

"GWS has got a lot of talent based in Sydney, a lot of talent and someone like Ross could come in and shape them right up.

"I would be nervous if I was John Worsfold at Essendon. It's a big one, now Ross Lyon is in the game, there would be some nervous board members.

"I just think Worsfold is on shaky ground.

"If the Bombers fail end of September ... there has been talk behind the scenes that potentially there's some factions trying to push Woosha out of the Bombers."

Worsfold has been touted as a possible contender to succeed Lyon at Fremantle.

Collingwood assistant Justin Longmuir is the early frontrunner for the vacant Dockers position, with Peter Sumich and Brad Scott other leading candidates.

The Giants currently sit sixth on the ladder and are in the box seat to earn a home elimination final given that they face the struggling Suns on Saturday night.

Cameron said he has spoken to his players about the importance of rebounding strongly from the two recent heavy losses.

"The last two weeks we dropped away pretty significantly and it was disappointing," Cameron said.

"Part of that (recent chat we had) is we want our fans to keep rocking up and seeing a really good side tackle every week head on.

"We feel as though we've done that, especially in the last four years."
