Jenny's day is usually spent on the sidelines watching sons Ryan and Lachlan chase their rugby dreams. This year will be more of the same, but different in so many other ways.

Why? Because Ryan will run on to Canberra Stadium wearing an ACT Brumbies jersey and Jenny's name will be printed on the back.

It's fitting because the term "rugby mum" doesn't quite do Jenny justice, just like many others like her. "Rugby mum" has meant being the taxi driver for the two-hour round trip from home to training, the team manager, the ankle strapper, the supporter and the nervous parent sitting in the stands.

Not bad for someone who didn't know much about rugby until her sons started playing, but Jenny wouldn't have it any other way.

"That will be a special moment to see those jerseys," Jenny says. "I'm incredible proud of my boys. What they've achieved has taken so much dedication and commitment.

"I don't know if I'll ever get used to watching them or worrying about them. But speaking to the other mums at the Brumbies, I think everyone is the same.

"There have been many a Mother's Day I've sat on the sideline watching the boys do Brumbies trials. But I couldn't think of anything better - surrounded by my boys and friends."

The Brumbies will honour the mums in their lives when they wear Mother's Day jerseys this weekend. It will hit home for three Canberra juniors who have been walking the same path for almost a decade.

That's why this Brumby Tale is about more than a player and the journey to get to Super Rugby. This is about bonds that start as teenagers and bring families together.

Ryan Lonergan will play the fourth Super Rugby game of his career when the Brumbies play the Japan Sunwolves on Sunday.

His close mates, Mack Hansen and Tom Ross, will play in the curtain raiser for the Brumby Runners as they continue their rise through the ranks.

The trio have known each other since they were 12 years old. Hansen and Ross were the Daramalan College best mates who always dreamed of playing for the Brumbies. Lonergan was the scrumhalf from the other side of town who made his way into Brumbies junior teams.

Along the way their parents, Jenny and Tom Lonergan, Diana and Craig Hansen and Bernie and Damian Ross, have created their own friendship group.

They've sat on the sidelines around Canberra and country NSW watching their boys in schoolboy tournaments and they've travelled across the world to watch them play for Australian junior sides.

Now they get a front-row seat in Canberra as they take the first steps in their Super Rugby careers, with 21-year-olds Ryan, Mack and Tom tipped to be the leaders of a new generation of Brumbies.

"I probably don't tell mum and dad enough about how much I appreciate their support," Lonergan said.

"But they've helped me so much to get to where I am. It's basically been a full-time rugby gig for mum. She'd drive us to training in the morning, then to school, rugby training in the afternoons ... and she was the manager at one points strapping ankles and organising everything."

Hansen, Ross and Lonergan first joined forces in the Brumbies under-13s representative side. They have since played at the junior world championships in France and all three were on the field at the same time in the Brumbies' win against the NSW Waratahs earlier this year.

The match doubled as Mack and Tom's Super Rugby debut and their parents were surprise guests in the change rooms to present their children with their jerseys the day before the game.

"I don't think mum and dad have had a family holiday in a long time, it's always been around rugby," Mack said.

"Sometimes you feel a bit guilty because you know how much mum and dad have had to miss out on in their own lives. But I think they get a kick out of it, and they've met great people as well like Ryan and Tom's families.

"With all the young guys at the Brumbies ... we're all excited for the future. We all back each other and have confidence in each other on the field.

"If you're not enjoying your footy, you're not going to play well. All of us have a joke around at training and take it serious when we need to. But I honestly still feel like I'm at school having all of the young fellas around."

Hansen and Ross have played almost all of their rugby together and were room-mates for the Brumbies' tour of South Africa and Argentina last month.

"I didn't sleep well for the entire two weeks. Tom is a terrible snorer ... the whole hotel was shaking. He's pretty bad and he's even had his nose fixed for it. He should get a refund," Hansen laughed.

Prop Tom, who has played three games in his rookie season says: "Mack still acts like he's at school. He's definitely the pest, always trying to make a joke out of everything.

"We've all been playing together since we were 10 or so. That's pretty cool. There's a good group of us who are around the same age ... you're seeing your mates every day. It's sort of got that family feel."

The Lonergan, Ross and Hansen friendship has outgrown the rugby sidelines. Jenny, Diana and Bernie have regular catch ups away from rugby road trips or training sessions.

"I think they had a Christmas shindig together ... mum is always sending texts to Jenny," Ross said.

"My parents and Mack's parents always catch up for a Friday schnitzel or something like that. With the Brumbies family feel ... a lot of brothers who have come from all over the place. If we can come together and gel, it has that different sort of feel. I've grown up with these guys and their families."

The dream, of course, is for the trio to be Brumbies starting players in the coming years. Right now they are content learning from those ahead of them and trying to earn more game time as they develop.

Lonergan is a former Australian under-20s skipper and has a bullet pass with a neat kicking game. Ross is the hard-nosed scrummager and Hansen is the back-line X-factor who glides with an eerily similar style to Wallabies great Stephen Larkham.

"When we played together earlier this season, that would have to be one of my best memories. It was really special," Lonergan said.

"It's comforting to see we're all working for the same thing. We're all hungry for game time and none of us have taken a back seat. We're all pushing and we want to play. We all believe we're good enough, and that's exciting."

But rugby is more than that for Diana, Jenny and Bernie. It's about sharing the ride with their sons and closest friends.

"They're living their dream, which is pretty cool," Diana Hansen said. "You couldn't be prouder of them and I'm just as proud of Tom and Ryan as I am of Mack.

"Rugby has been like an annual holiday for our families. I pinch myself all the time, and I think Mack does as well, but there are many good times to come."
