Three Tests into the Rennie era, the All Blacks have swept France, Italy, and Ireland — and their new coach believes they're still well short of their ceiling. Rennie was particularly pleased with the balance against Ireland: dominant set-piece, disciplined ball retention, smarter kicking, and a markedly improved defensive structure compared to the France game. His pointed acknowledgement that South Africa is 'a different beast' — noting the Boks put out a 'B side' and still beat Scotland — signals he's under no illusions about what's coming. Crucially, Rennie frames the Rugby Championship tour as a development opportunity regardless of results, suggesting he's building toward a longer-term game model rather than chasing short-term wins. For Springbok supporters, the piece is worth reading for Rennie's candid assessment of where the All Blacks stand and the specific areas he believes still have room to grow — useful context heading into what shapes up as a high-stakes series.
