Chief executive Steven Trigg presented Johncock with life membership at the Crows' season launch on Tuesday night and used the opportunity to reveal chairman Rob Chapman's boardroom declaration that Johncock would claim the Brownlow in 2011.
The 28-year-old was arguably Adelaide's most valuable player last season but missed seven games through injury, which prevented him from challenging best and fairest winner Richard Douglas for the club's highest individual honour.
He fell 10 votes short of Douglas to finish in fifth place - his fifth top-five finish in the Crows' club champion award in 10 years.
Johncock has only polled 29 Brownlow votes in nine seasons in the AFL and said he was more focused on the team's performance than winning an unlikely Brownlow Medal.
"I was a bit surprised by [Chapman's comments]… maybe Rob had a bit too much to drink," Johncock said on Wednesday.
"There's always room for improvement… but if I just go out there and play my role within the side, I'll be happy."
Johncock has played 184 games since being picked up by Adelaide with pick No.57 in the 2000 NAB AFL Draft.
The rebounding defender has had his share of troubles over the past decade.
In 2008, he was sent back to the SANFL for two weeks after failing to meet the necessary standards of preparation and also enrolled in a six-week lifestyle and management course to address a number of personal issues.
Last year, Johncock was barred from selection for one game as punishment for missing a weekend rehabilitation session.
The classy backman is out of contract at the end of the season, but said he was keen to repay the club's ongoing faith by playing out his career at West Lakes.
"There were times in my career where I had some issues off-field…but the club has always been very helpful in helping me through those difficult times," he said.
"If it wasn't for the club actually putting the time and effort into me to put me on that right path…I guess any other club would have got rid of me straight away.
"I'm very grateful for that and the only way I can repay the club is trying to do what I do best and that's on the field. I've been around here a long time so I wouldn't want to go anywhere else now."
Johncock's ability to stay fit will be vital to Adelaide's finals aspirations this season, following the retirement of creative half-back flankers Andrew McLeod and Simon Goodwin.
However, the one-time club leading goalkicker said he was hopeful of breaking out of the backline on occasion in 2011.
"Ever since Craigy [coach Neil Craig] has taken over, I've always been touted as just a back pocket, or a back line player," Johncock said.
"Probably, the last six or seven years I've been playing down back so I'd like to see myself go up forward every now and then. That would be nice."
Trigg also used the season launch to take a swipe at respected journalist Mike Sheehan, who failed to include a single Adelaide player in his list of the top 50 players in the competition.
Johncock denied the players were fazed by the snub.
"We know where we stand in the competition. Nobody has probably given us a hope in hell but we're definitely looking forward to the year with great excitement," he said.
Graham Johncock is a $359,100 defender in the Toyota AFL Dream Team competition.
