The 22-year-old was sent to train with WAFL club Swan Districts early in 2012 after failing to meet the club's minimum fitness standards.
Following an extended period in exile, Walters returned to the club become one of the Dockers' most influential players, kicking 68 goals in his past 31 matches - including 46 this season.
It was a feat that saw him named in the All Australian 40-man squad this year.
Walters said he was sick of talking about that dark period of his career, preferring to use the experience to help mentor youngsters such as fellow Docker Josh Simpson to ensure they did not suffer the same ignominy.
"I'm kind of over everyone talking about it," Walters said.
"That's in the past. It's two years ago. I reckon I've changed a lot on my game and having a baby made me change all that and I'm kind of just over it now. So I'm trying to move on.
"Everyone talks about Josh Simpson.
"I'm just trying to help him because I never really had anyone to help me. I don't want the same thing that happened to me happen to him as well so I'm trying to help him out as much as I can."
Simpson, from the remote town of Yalgoo, 500km north-east of Perth, was taken by Fremantle with pick No.17 in the 2012 NAB AFL draft.
He suffered from homesickness during his first season at AFL level but did make his debut in round 23 against St Kilda, his only game of the season.
After Simpson battled through the first week of the pre-season, Walters believed the 19-year-old had begun responding to the advice from the senior players.
"He's much fitter than he was the first week," Walters said.
"There's no doubt he's got all the talent in the world. It's just the hard work component now. I had to find it and now he's starting to find it."
The Dockers trained strongly on Monday in the summer heat in Perth. Walters said the players had delivered on their pact to return to training in good condition.
"From last year, the grand final, the boys really wanted to come back fit and firing," Walters said.
"We had a strict target the boys wanted to come back at and I think most of the boys have come back in good condition."
Hayden Ballantyne was the only notable absentee after his partner gave birth to a baby girl on Saturday night.
Being a young father himself, Walters had some simple advice for his close mate.
"I said 'Your life's going to change from here, just enjoy it'," Walters said.
"He's still going to be the same old Hayden on the field, I reckon. Just a bit more grown up away from it."
