New Zealand put in a memorable performance in Hamilton in the rain that got them back on top of the Rugby Championship table, while Argentina seemed to resort to form after their memorable win last weekend, by suffering a blowout loss to the All Blacks a week later. Meanwhile, a Springbok side clearly nursing a grudge against the Wallabies and Nic White in particular put on an edgy and bruising display that allowed Australia very little say in proceedings. With New Zealand and South Africa looking once more the tournament favorites, but with consistency simply not a feature of this year's tournament, anyone could still win it as we look towards Round 5.
