When a coaching legend walks away from one of schoolboy rugby’s most successful dynasties to chase a new dream, you listen. Sean Erasmus’s emotional farewell to Paarl Boys High marks the end of an era. But as the final episode of the year of The Rugby Factory, proudly brought to you by Bossa, revealed, this isn’t a retirement, it’s a rebirth.

In a candid conversation with Andy Daniel, Erasmus peeled back the curtain on a remarkable coaching journey that, flourished through faith, and now enters an exciting new chapter as head coach of Maties. His story is one of humility, perseverance, and the unshakeable belief that building young men matters more than building trophy cabinets, though he’s done plenty of both.

The “accidental” coach

Every great journey has a starting point, and Erasmus’s couldn’t have been more unexpected. Fresh off a playing career at Harlequins in Durban that was cut short by a back injury, he wandered into Grosvenor Boys simply looking for a part-time gig.

“I remember when I walked in there, the coach was sort of leaving and he said good luck, you are coaching now,” Erasmus recalled with a laugh. “I was sort of just looking for a part-time job asking where can I help out and he said no, you’re the new first team coach. Karen (Sean’s wife) and I laugh about it, how she was the breadwinner looking after me and how much I enjoyed it. Now we’re here and Karen is still the breadwinner.”

That self-deprecating humour belies the fierce competitive streak that would define Erasmus’s coaching philosophy. But first, there was Glenwood.

The Green Machine roars

Erasmus coached at Glenwood along with the Molnar brothers, Andras and Phillip, who now coach at Stellenberg and Diamantveld respectively. What followed was nothing short of a golden era as the Durban school climbed the rankings to become a top-five force in South African schools rugby.

The key? Total buy-in and the freedom to dream big.

“Tony Pinheiro, who is the headmaster at DHS now, just absolutely backed me and told me do what you need to do. We tried all different things. I just loved the freedom that came with it, in the sense of we are going to dream in a room but we’re not just going to leave it in a room, we are going to chase it,” Erasmus explained.

“The whole Green Machine family and community got behind the school. It was such an easy transition to get the school to a top-five school in SA at the time as everyone was behind the school.”

Erasmus didn’t just coach the first team, he coached almost every single side in the school on his way to taking the lead with the first. Along the way he was building a culture from the ground up. And when Glenwood beat the mighty Paarl Boys High at Wildeklawer, led by a young captain named Thomas du Toit, something shifted.

“Just the way he carried himself as a captain said a lot to me about who Boishaai was as a school, and that was my thing, working with a traditional boys school,” Erasmus said.

The blue and white dynasty

In 2012, Erasmus was on his way to sign on for the job at Monument. It didn’t work out and the call came from Paarl Boys High. Erasmus was reluctant, fiercely loyal to Glenwood, but while doing his Level 3 coaching course in Cape Town, he agreed to an interview.

The rest, as he pointed out, is truly history.

What Erasmus and Boishaai achieved over the following years redefined schoolboy rugby dominance:

• 185 matches
• 153 victories
• 13 defeats
• 2 draws
• Unbeaten between 2015 and 2017
• 119 u.18 players represented Western Province
• 42 players represented South African Schools teams

The numbers are staggering, but Erasmus deflects credit with characteristic humility.

“You just think of the hard work that the boys put in just to get there. It’s a proud moment when you see the boys donning Western Province colours. It just feels like that team effort back home, all the coaches involved from u.14 all the way up make that special for the boys. I was just fortunate enough to be the leader of that group at that time. It’s definitely a team effort.”

The Lions lesson

Success breeds opportunity, and in 2018, the professional ranks came calling. The Lions offered Erasmus a chance to fulfil every coach’s dream, coaching at the highest level. He left Boishaai, but the move didn’t work out as planned.

For years, Erasmus stayed quiet about what happened. But in this interview, he offered a brutally honest reflection.

“I’ve been so quiet for so long about the Lions thing. Reflecting on it, maybe I wasn’t ready for that. In 2018 at Paarl Boys, I had just become head coach of SA Schools, head coach of the Craven Week side. I was involved with Western Province u.19 Currie Cup side and maybe it was the wrong timing,” he admitted.

“I think maybe at that time it was about me, and about my aspiration and what I want to chase. It wasn’t the right time for God at that time. We all have that dream to coach at the highest level, but I wasn’t ready, and in hindsight maybe I wasn’t good for the Lions because I wasn’t ready for that responsibility.”

That vulnerability, the willingness to admit he wasn’t ready, that his timing was off, that perhaps he’d chased his own ambition rather than divine purpose, speaks volumes about Erasmus’s growth as both a coach and a person.

The family loved Paarl, and when Boishaai called him back, there was no hesitation. Until now.

The Maties challenge

“Everyday I get into the car and I’m not wearing something blue, I wonder if I’m doing the right thing here,” Erasmus confessed about his move to Maties, whose maroon colours contrast sharply with Boishaai’s iconic blue and white.

But this isn’t about doubts, it’s about purpose.

“Someone once prophesied on my life saying that I would be working with young people and there would be a responsibility there. Winning hearts for Jesus is more important than winning games. I always struggled with that identity in my head because I would love to coach a professional side, but God destined this thing.”

“Now it is the right decision. There is also an opportunity at Maties to do something positive. Schoolboy rugby will remain something special for the main reason, because of that connection and relationship that you can build with a young person. A lot of young people don’t have someone that speaks into their lives anymore and they need someone to confide in. Things have changed for young men. There is a lot of pressure.”

At Maties, Erasmus faces a new challenge: competing for the Varsity Cup and elevating one of South African rugby’s most storied programmes.

“It’s all about trying to think outside the box, and find an edge again about how this game is played at this level and what we can do differently and be exciting at the same time. How are we going to take Maties rugby to the next level?”

Sitting in the iconic Danie Craven Stadium, Erasmus feels the weight of history.

“Just walking in at the bottom there, you are part of the guys that started rugby. It is special and there is a great deal of responsibility that comes with it. I’m excited to see the Danie Craven full and make everybody proud.”

A Legacy beyond trophies

As The Rugby Factory’s final episode of the year draws to a close, Erasmus leaves listeners with the same message he hopes to leave with every young man he coaches:

“Be strong and courageous. I hope that is something I can leave behind for everybody.”

From an “accidental” coaching gig at Grosvenor Boys to building the Green Machine at Glenwood, from creating a Boishaai dynasty that will be remembered for generations to now chasing glory in maroon at Stellenbosch, Sean Erasmus’s journey proves that the best coaching careers aren’t measured solely in wins and losses.

They’re measured in lives changed, young men built, and the courage to follow your calling even when it means walking away from unprecedented success to start all over again.

Sean Erasmus’s currency is measured in the hearts and minds of young men who will carry his lessons long after their playing days are done.
