LEVI Greenwood has turned his career on its head this season, going from fringe player to one of the first Roos picked each week, but the North Melbourne midfielder admits he's not entirely sure how he's done it.
 
Greenwood entered this season with his career at the crossroads.
 
He had played just 11 games in the previous two seasons and was entering the last year of a three-year deal he signed in June 2011.
 
But since racking up 13 possessions in less than a quarter as North's substitute against the Western Bulldogs in round two, Greenwood has re-established himself as a key member of the Roos' emerging team.
 
Greenwood has still played the run-with roles he played in the past, but has also been one of North's biggest inside ball-winners in 2014.
 
The hard-nosed midfielder told AFL.com.au this week he was rapt with his start to 2014.
 
But when asked how he had turned his career around, he admitted: "I'm not too sure."
 
"I guess that my back was against the wall a bit.
 
"I trained really hard in the pre-season and I've been given a better chance this year, a bit more freedom in my role.
 
"It's nice that the coach (Brad Scott) has a bit of faith and plays me week-in (week-out) now, so it does make it a bit easier.
 
"I've got a good understanding of what my role is now and Brad has got confidence that I'm going to play it every week."
 
Scott's confidence in Greenwood is well founded.
 
In his nine full games since round two, Greenwood has averaged 26.2 possessions a match and, despite being overlooked for round one, is ranked second at North for centre clearances, third for clearances and contested possessions, equal third for inside 50s and fifth for tackles.
 
The uncertain future that he faced at the start of this season now looks far brighter, with Greenwood revealing his manager Liam Pickering is in talks with the Roos about a contract extension.
 
Not that Greenwood is going to let those negotiations become a distraction.
 
"I spoke to my manager a few weeks ago and I think they're talking now, but I'm not too fussed, I'm sure it will work itself out," Greenwood said.
 
"I'm just trying to focus on playing good footy at the moment and all the other stuff will sort itself out hopefully."
 
Greenwood thought he could be on his "last chance" when he was recalled against the Bulldogs and endured a nervous first three quarters on the bench that afternoon.
 
He was relieved to play so well when he finally got his chance, modestly saying he took advantage of the fact the game had slowed down by the time he came on early in the last quarter.
 
Despite his consistent form since, Greenwood's memories of his lean 2012-13 seasons will ensure he does not take his senior spot for granted.
 
"It's been tough, it's been really hard," he said.
 
"You're slugging away in the seconds getting a game here and there, I just couldn't get any consistent games.
 
"I was only ever in for two or three games and then I was back out again.
 
"It's been nice to get a good run at it and I do appreciate my spot in the side for sure."
