You know who your current AFL captains are. But who is next?

At last week's AFL Captains' Day, AFL.com.au surveyed all 18 club skippers (or their deputies) to discover who they anticipate they will one day be handing the reins of leadership to at their teams.

From those earmarked from a long way out, like Harris Andrews at Brisbane or Andrew McGrath at Essendon, to those a little less predictable, like Irish recruit Mark O'Connor or tough midfielder Tom Atkins at Geelong, the answers are expansive and very interesting.

Here is who your current skippers believe will be their clubs' next captain.

Adelaide

"I love Brodie Smith. I think he's got plenty to give in that area. But also Tom Doedee, another one of our young kids, and Darcy Fogarty as well." - Rory Sloane.

Brisbane

"If you were a betting man it's probably Harris Andrews, but I think Hugh McCluggage, Jarrod Berry and Alex Witherden are all putting their hands up at the moment to be the next captain for whenever I hang up the boots. But probably Harris. He's been a fantastic vice-captain for me and he's a fantastic leader and a great human." - Dayne Zorko.

Carlton

"Hopefully they don't knock Paddy Cripps or myself off our perch for a little bit, but we've got a bunch of really good leaders coming through. The two young guys who have been brought into our leadership group this year, Jacob Weitering and Sam Walsh, they'd probably be the next two. They'll be earmarked for a succession plan after us. However long that is, I don't know. 'Walshy' is in the leadership group in his second year, so he's going well. We're blessed as a footy club to have some strong leaders coming through." - Sam Docherty.

Collingwood 

"Maybe Taylor Adams, Darcy Moore or Brodie Grundy … probably one of those three guys. If not, Steele Sidebottom or Jeremy Howe. We've got a number of guys who could do it." - Scott Pendlebury.

Essendon

"There are a few in line, I reckon. We've got an awesome calibre of leaders developing, so someone like Andy McGrath is one." – Dyson Heppell.

Fremantle

"Andrew Brayshaw. He's well-rounded, well-liked, keen to learn, adaptable, a good listener and he's just going to become a really rock-solid player for us." - Nat Fyfe.

Geelong

"We've got some great candidates. Mark Blicavs, Paddy Dangerfield, Tom Stewart … they all display really good club values. We've got some good young leaders coming through in Mark O'Connor and Tom Atkins as well. A lot of players have the ability to be captain. It's obviously a really challenging job at times and I think Joel Selwood does a phenomenal job and will probably do it until he retires. We're working on everyone becoming a better leader from the bottom up." - Mitch Duncan.

Gold Coast

"If it's not Jarrod Witts as a standalone captain, then probably Touk Miller. His standards around the place are so professional and he says all the right things. He loves the place, so he's definitely a captain-in-waiting." - David Swallow.

GWS Giants

"Tim Taranto." - Stephen Coniglio.

Hawthorn

"The great thing about our club is that we have a number of leaders who can step up. Guys like Isaac Smith, Jaeger O'Meara, Liam Shiels, Ben McEvoy." - Tom Mitchell.

Melbourne

"Jake Lever." - Max Gawn.

North Melbourne

"I reckon we have a couple of guys in line. There are some guys coming through in the leadership ranks. Trent Dumont is a guy who has really improved in that area. Jy Simpkin, as well, as a young guy who is coming in and starting to have an impact on games. The way he goes about it, you can't fault him. Jy's not what you'd call a big personality, but the way he goes about his footy is outstanding for a kid of his age. He just turned 22 the other day and he almost carries himself like he's 28. The way he trains with intensity and intent, the way he plays his footy, the way he carries himself … it's first-class. He'll learn his craft over the next few years, in terms of leadership and how to improve and what he wants to work on, but the way he goes about it is first-class." - Jack Ziebell.

Port Adelaide

"We've got Darcy Byrne-Jones and Tom Clurey, who are only a few years below me. But they are really important to our culture." - Tom Jonas.

Richmond

"I haven't even been named captain yet. I'm incredibly lucky and grateful for the support I receive as captain, but there are so many guys that are of a similar age or a little bit younger that have great attributes and could easily be in my role. There are some really good young guys as well. I actually couldn't tell you who the next captain would be, there are a number of guys that could well and truly do the job. I'll have a few more greys, then I'm done." - Trent Cotchin.

St Kilda

"Tim Membrey is someone who has really grown in that space. He's got that leadership style a lot like Jarryd Roughead, who is really able to empathise with his teammates and really connect on a 'good bloke' level. His footy does the talking as well. I'd love to play under him." - Seb Ross.

Sydney

"I think Callum Mills. He's just uncompromising in the way he goes about it, on and off the field." - Josh Kennedy.

West Coast

"Liam Duggan." - Luke Shuey.

Western Bulldogs

"The obvious one is probably Josh Dunkley. He's quite a conscious person of the direction of the football club and of others." - Marcus Bontempelli.
