Or 5 in the last 20 years (for a combined 10 years of captaincy).Graham Farmer - Geelong (1965-67)

Six. Just six indigenous captains in a league that has spanned more than 120 years...
20 seasons equals a potential 335 years of captaincy, if all teams had only one Captain at a time.
10 out of 335 equals bang on 3%, about right in terms of per population.
I know some teams having multiple captains makes the above inaccurate, but it probably shows that in the modern AFL era it is probably not the issue it used to be.
