The Boks head to Turin knowing a loss to Italy, combined with the All Blacks avoiding defeat at Murrayfield, hands number one to New Zealand. Due to the 14.79-point rating gap, South Africa can't gain ranking points from a win over the Azzurri — so the fixture is pure risk with no upside. Italy, sitting 11th, could leap to ninth with a win, while the Boks can't fall below second even if they lose. Elsewhere, the weekend has serious movement potential across the top ten: France risk dropping to eighth for the first time since 2019 if Fiji cause a shock; Ireland could slide two spots if France and England both win; Australia and Scotland both have a path to third depending on results; and a heavy Argentina win in Dublin paired with an England loss could send England tumbling to eighth. The piece maps every result permutation with precise rating point shifts across both the Nations Championship and Nations Cup fixtures.
