SANFL Coaches in Waiting

A hypothetical question:
If, at the end of this season, two league level coaching positions were vacant at the 9 SANFL clubs, who are the coaches in waiting to fill those positions?
An assistant coach/reserves coach at an SANFL club?
A former SANFL coach?
An amateur league coach?
A retiring or recently retired SANFL player?
A retiring or recently retired AFL player?
Someone from another league - WAFL, VFL, U/18s, TFL, NTFL, QFL, ACTAFL?
The reason I pose this question is that the dilemma for the SANFL is getting a quality coach who is gonna stick at it for a while and not necessarily use the SANFL as a springboard to other opportunities that may arise at a higher level.
