Sanderson was dismissed by the Crows on Wednesday afternoon with two years left to run on his contract.
The Crows' decision has created speculation former club captain Simon Goodwin will be lured back to West Lakes, after being sounded as Paul Roos' possible successor at Melbourne this week.
It also promoted the natural link between Sanderson and Buckley – who are former housemates and remain close – and the possibility of the sacked Crows' frontman joining the Magpies next season.
But AFL.com.au understands the Pies are happy with their set-up and if anything are downsizing in numbers.
The club recently told forwards coach Matthew Lappin his contract would not be renewed as it prepares for life under a football department spending cap.
Sanderson will front the media in Adelaide on Thursday afternoon but chairman Rob Chapman will also conduct a separate media conference on Thursday morning to fully explain the club's sacking of its coach.
He played 209 matches with Adelaide, Collingwood and Geelong between 1992 and 2005, and was appointed coach of the Crows in 2012.
