The head coach’s chair at a Powerhouse Five school — Affies, Grey College, Paul Roos, Paarl Gymnasium and Paarl Boys’ High — is South African schoolboy rugby’s most coveted job. It comes with profile, prestige and a healthy pay packet. What it does not come with is breathing space. There is nowhere to hide. This is one of the most unforgiving job markets in South Africa, where the margins are microscopic and expectations escalate by the season.
The 2025 season underlined just how tight the PH5 ecosystem has become. Between them, the five schools they played highly entertaining, relatively close test matches against each other and lost only two matches to teams outside their inner circle — both were away defeats to a superb Oakdale outfit. Outside challengers will always rise, but sustaining that challenge is what separates contenders from pretenders. In recent years, only Garsfontein have managed to maintain a presence as a first XV consistently knocking on the door. Oakdale set the standard in 2025, but history suggests maintaining that level year on year is the real test. The Riversdale farm school should threaten again in 2026, but a dip beyond that could easily see them slide out of the Top 20 by 2027.
Which means the reality heading into 2026 is stark: the PH5 remain overwhelming favourites to occupy at least four of the national top-five spots. With that dominance comes pressure — and plenty of it. Here’s how the heat stacks up for each head coach.
1. Corné Uys (Paul Roos)
Corné scaled the summit in 2024. An unbeaten season, capped by a commanding victory over Grey College at Markötter, is the coaching equivalent of Olympic gold — forever etched, never diminished. That 2024 campaign elevated his standing and earned him significant credit in the bank.
But elite rugby is unforgiving. Despite boasting size and talent, 2025 was a sobering PH5 reality check for the Maroons. Paul Roos lost all four PH5 encounters — three by a single score, including a 10-point defeat to Boishaai. Fine margins, yes — but results still rule. Stellenbosch expects rebounds, not explanations, and 2026 will be viewed as a corrective year.
2. Jannie Geldenhuys (Grey College)
In an era of semi-professional schoolboy rugby, Jannie remains a rarity: a classroom educator, deputy headmaster and head coach at his alma mater. That alone commands respect.
Grey’s 2023 unbeaten campaign — including a PH5 Grand Slam — reaffirmed their status as South Africa’s premier rugby school. But with that reputation comes a brutal truth: anything short of perfection feels like failure. To crack Grey’s all-time top 20 teams, an unbeaten season is effectively the entry requirement.
Grey’s greater concern may lie in their thinning depth across PH5 derby fixtures. Full dominance beyond the A-team may be unrealistic, but remaining competitive across the programme — and protecting a credible win-loss record on the biggest days — is fundamental to who they are.
With a new forwards coach on board and a new Director of Rugby set to add further coaching weight, and the highly regarded Bobby Joubert already adding significant value as Head of Rugby, the support structure is formidable. The flip side, however, is accountability. In a fiercely competitive PH5, the pressure on Grey to deliver in 2026 will be immense.
3. Pieter Rossouw (Paarl Gymnasium)
If there is a household name in schoolboy rugby, it is Pieter Rossouw. Widely regarded as the best in the business, he enters 2026 with what many insiders see as the strongest title credentials.
Gim’s rugby blueprint is arguably the gold standard, and they head into 2026 as favourites, bolstered by a strong core of returning, experienced u19A campaigners.
The main obstacle is Paarl Interskole.
That final clash with Boishaai is rugby’s ultimate lottery — where form, rankings and logic routinely mean nothing. In 2025, it became the title decider, slipping away by two points. And therein lies the cruelty: Gim’s entire season is judged on one afternoon.
Finishing second in 2025 was no small achievement. Since 2010, Gim have managed just two second-place finishes, alongside two national titles. Yet pressure remains relentless, especially with the departure of highly rated forwards coach Helmut Lehmann to the professional ranks at Western Province and the Stormers.
4. Ruan Jacobs (Afrikaanse Hoër Seunskool)
The youngest coach in the PH5, Ruan’s stock continues to rise — so much so that he sits firmly on the Bulls’ radar. The departure of twin brother Neill to Loftus increases his workload, but Affies’ systems are famously robust. The machine will keep running.
Affies cleared a major psychological hurdle in 2025, showing the grit to come from behind to draw with Gim and then close out a tight win over Paul Roos. Their forward packs remain outstanding — dominant, disciplined and brutally effective.
The lingering question is out wide. Despite regular front-foot ball, the backs have too often gone missing in the biggest tests. Coaching evolution is required to turn opportunity into knock-out blows. With a knowledgeable and demanding supporter base fully aware of the squad’s quality, the pressure to reclaim the national No.1 ranking will only intensify in 2026.
5. Sean Erasmus (Paarl Boys’ High)
A coach with one of the highest rugby IQs in the school game, Sean reclaimed top spot in 2025 — a welcome return to the summit after a lean spell, particularly a bruising 2024 with a young side that suffered a record defeat to Gim. The title meant Boishaai head coach now holds four national No.1 finishes, more than all four of his PH5 counterparts combined.
While 2025 fell one result short of matching the golden, unbeaten local run of 2015–2017, it restored Boishaai’s authority. Heading into 2026, Erasmus arguably carries the least immediate pressure of the PH5 coaches.
Yet vulnerabilities remain. Boishaai are widely viewed as the most likely PH5 side to stumble against an outsider — and one slip could see pressure surge back swiftly. Complicating matters is the vacant Director of Rugby role following Neil de Bruin’s move to the Bulls, leaving Erasmus to juggle increased responsibility while rebuilding a squad with only two regular starters returning.
The Verdict
The PH5 remain South African schoolboy rugby’s iron core. But dominance breeds expectation, and expectation breeds pressure. In 2026, reputations will be tested, legacies nudged, and patience stretched to its limit. In this arena, second place is rarely enough — and excuses, as valid as they may be, do not survive the winter.
