The 24-year-old was a member of Melbourne's 2006 leadership group, but took on a lesser role last season before being elevated again this year.
Miller considers himself "possibly more suited" to the Demons' new values, which have seen him named as one of David Neitz's deputies along with Russell Robertson, Cameron Bruce, Adem Yze, Brock McLean and James McDonald.
"I don't think I've changed between this year and last year," Miller told melbournefc.com.au.
"I've just gone about it the same way, and maybe just because the values of the group have changed a little bit, or we've decided we want to stick to something a little bit different to last year, I'm back on the guys' radar.
"I was a little bit surprised, but because we went through a process, it didn't hit me all at once. But, it was something that took a bit of time and now it's good. Really good."
Miller believes he provides leadership through his attitude on both the field and on the training track, which was reflected in his teammates' decision to vote him back in.
"I'm just the person that I am around the club and out on the track. It's not up to me to decide if I'm a leader or not; it's up to the people around me," he said.
"I think I represent what we're trying to achieve on the track; I think I set a good example out on the track, and guys see that. It's something that I constantly find myself looking at.
"I think the reason I got voted in was because I have been displaying the qualities that we want to stand for this year out on the training track, and I think it's something that has looked after itself.
"I haven't pursued [the leadership role], and I haven't really done anything that I wouldn't have done last year. I just think that I've displayed those qualities."
Taking on the top job once Neitz has given the game away is not something that Miller has on his radar, although it's a position he wouldn't pass up if it was handed to him.
"To be honest, I don't really think about it. I don't have any aspirations to be captain; if it happens, it happens," he said.
"If you're the best person for the job, and I think it, the guys think it and the coaching staff think it, then it will just happen. I don't have to pursue it."
As far as pre-season is concerned, Miller said he can't remember a lead-up as anticipating as this one, with the Demons working within what he described as "almost a new club".
"I've only really had the one coach, so for the first three or four years, I was just finding my feet as a young guy," he said.
"Then, as I've been in the system a little bit longer, I can kind of step back and say this is as exciting and as positive [experience] as we've had in a pre-season."
He also said the contrasting ages of the players on the list is creating a buoyant atmosphere.
"We've still got a good mix of older guys, but the youthful exuberance of the young guys in the group is just infectious," he said.
"We've got a lot of young guys that are taking the next step currently in their careers, and it feeds through all of the older guys and it drags them along and gets them up onto the same level, excitement-wise.
"They're all really excited about our footy, and they're really keen to stamp their mark on the side, so it's all really positive."
Not surprisingly, Miller is more interested in the start of the actual playing calendar than more running drills, despite the tough nature of the Demons' first assignment.
The side is set to kick off its NAB Cup campaign against the reigning premiers at Skilled Stadium on February 16.
"It can't come quick enough, although it's only three weeks away now," he said.
"Once you start playing practice matches, it's already here. I can't wait to start playing; I think it's going to be great. I really am looking forward to playing games again."
