ASK Port Adelaide people who the club's greatest coach is and you're sure to get a myriad of responses.
As a player he featured in great teams.
Retiring as a player in 1973, Cahill immediately took on the senior coaching of the Magpies following the retirement of the legendary Williams.
Cahill went about the process of crafting a Port Adelaide side capable of winning premierships.
Star-studded lineups were made and, in 1977, Port’s long premiership drought was broken when the black and whites triumphed over Glenelg in the grand final at Football Park.
It would be the first of ten flags in the SANFL for Cahill and the establishment of two amazing periods of success for the club.
Cahill would coach the Magpies to three more flags between 1979 and 1981 and, at the end of the 1982 season, took up the offer to move interstate and coach Port Adelaide’s ‘sister’ club in Collingwood - the Victorian Magpies.
After two seasons with Collingwood, he would return to Adelaide and take up the senior position at West Adelaide before returning to Alberton for the 1988 season.
The Magpies dominated proceedings for eight years - winning six flags under Cahill.
There was no doubting Cahill’s ability to get the most out of his players.
The Williams-Cahill connection was highlighted again shortly after 1996.
The reason Cahill left the top job midway through that season was to focus on the club’s transition from the SANFL to the AFL, where he would coach the newly coined ‘Power’ for its historic first season in the national competition.
Under his stewardship, Port Adelaide would narrowly miss the AFL finals twice.
Then in 1999, Cahill’s other apprentice, Mark Williams, would assume control of the Power.
There was never any doubt of Cahill’s ability to get the best out of people - whether it be his players in the heat of battle or his apprentice coaches who would go on to achieve their own grand success.
Such is the esteem that he is held in within football circles that he has a room at the Adelaide Oval named after him - jointly shared with another Port Adelaide product and successful Fremantle and Crows player Andrew McLeod.
