Co-captaincy - is it a good thing?

[Dry Rot]

I see that the Swans have reverted to having co-captains again and from memory, a few other teams use this arrangement. See http://www.afl.com.au/news/2018-12-1...aptaincy-model

Is it a good system? And if you think it is, should we use it and who would be our co-captains?
