Yeah, whilst I believe in players being able to have a voice & certainly a vice capt for back-up I dont agree with the way many teams have so many cooks to one pot. After picking a capt, vice capt, emerging capt, most experienced player, leadership group, etc, etc you end up with maybe 2-3 players who are just players. Its all a bit of overkill.
Capts come in many different forms & styles so I dont believe there is one particular set of attributes that really makes a capt. I just think that when it comes to selecting a capt you just need to have a really good idea of the sort of team you've got personality wise & match that to a player whose personality you know is going to have the playing group motivated to follow them as capt.
