There was a rumour in the late '70s or early '80s that Darrell Cahill wanted to transfer from Port to Glenelg. Jack was coach at the time and Darrell was (probably still is) a very good golfer at the Glenelg golf club.
Anyway, the story goes that Cahill's Mum rang the club and said don't be stupid, he's playing for Port.
I doubt whether there's any truth in it at all but it was funny at the time.
By the way, has anyone ever heard Darrell speak in public ... he was the SANFL version of the Flying Doormat!

Dunno, I’m just an idiot.
I’m only the administrator of the estate of dedja … my yes be yes, my no be no
I love the smell of naphthalene wafting from Lefevre Peninsula during the finals
