Plucked from rugby obscurity by ACT Brumbies coach Jake White, Mogg is knocking on the door for Wallabies selection after a blistering start to his second Super Rugby season.

Mogg has revealed he was all but resigned to giving up his rugby dream in Canberra and was ready to move back to Brisbane to finish his degree as a secondary teacher.

That was until he received the phone call from White that changed everything.

Two years ago, ''I would put fuel in my car to get to training and then we'd buy bags and bags of rice and live off that for seven days,'' Mogg said.

''I try not to let it [Super Rugby] change my life … I don't want to get caught in the hype.

''I just want to stay the same person I was before I started playing for the Brumbies, and not change because I'm getting paid to play rugby.

''The main thing for me is I know I can't take anything for granted. I'm still learning a lot of things. Eighteen months ago, I wouldn't have dreamed of this.

''I still pinch myself every day and realise how lucky I am. and that I have to keep working.''

Wallabies coach Robbie Deans has been watching Mogg's form.

The 23-year-old was a raw talent in his debut season, and he made some on-field blunders.

But Deans was impressed enough to invite him to a Wallabies training camp.

But White doesn't want the Wallabies to rush Mogg's development.

He's scored three tries in three games. In the clash with the NSW Waratahs last week he set up another two tries. His lightning pace and booming left boot are the biggest weapons in his game.

Mogg's sporting background began in athletics when he was was a 100m and 200m track star at school in Brisbane, with the 110m hurdles his favourite event.

It was a schoolmate who suggested he join the rugby team, ''and I was the skinny, fast kid they put on the wing''.

He progressed to the First XV and was then recruited by the Brisbane Broncos rugby league team to play under-20s.

Mogg switched back to rugby union and moved to Canberra, playing two years of club rugby with Wests before almost giving up. Brumbies teammates call him ''Greyhound'' because of his slender build and long-running stride, and they have likened him to club legend Joe Roff.

The biggest challenge for Mogg has been bulking up so he could handle the Super Rugby workload and physicality. He arrived in Canberra at 79kg.

''Moggy said to me the other day he had to think about what to do last year, but this year he just knows,'' Brumbies captain Ben Mowen said. ''That shows how this whole group is developing, and Moggy is a key part of that.''
