SEN Breakfast host Garry Lyon believes North Melbourne, Carlton and particularly St Kilda should have a serious look at Collingwood assistant Justin Longmuir for the vacant head coaching positions.

Longmuir is highly regarded among the coaching ranks according to Lyon, and he believes clubs would be foolish not to consider him.

“I reckon this is a name, this is what I keep hearing anyway, Justin Longmuir,” Lyon told SEN Breakfast.

“He’s highly, highly rated and regarded. I don’t know if he’s got his hand up for any of these jobs.

“He came to Collingwood and helped their ball movement enormously, he had a big impact at West Coast and was at Fremantle as well.

“Just a career coach and people tell me he has all the credentials to be a senior coach. So there’s a name out of left field.

“He was very highly rated and West Coast was very disappointed to lose him is my intel.”

The former Fremantle forward was with the Eagles from 2011-2017, and was their senior assistant coach before moving to Collingwood at the beginning of 2018.

Despite Lyon's suggestions, SEN journalist Sam McClure understands the Saints job will go to either Brad Scott or Brett Ratten, who has been named as the club's caretaker coach for the remainder of the season.
