A big factor in why the Chiefs looked a vastly improved side in the last 30 minutes of their victory over the Hurricanes in Hamilton can be found in one significant second-half substitution.
Until then the visitors were clinging on and a boilover was not out of the question. But then on ran Ben Tameifuna, a man as big as a fridge and harder to shift. The Hurricanes quickly found themselves frozen out.
The tighthead prop, all 140kg of him, made his presence felt after replacing Ben Afeaki - himself in the form of his life and with a recent All Blacks debut to prove it - in a scrum five metres from the Hurricanes' line. Ben Franks and Co had managed to win their own feed after wheeling the scrum - a debatable decision by referee Garratt Williamson.
The Chiefs' reaction, with Tameifuna in the vanguard and helped by fellow newcomer, hooker Mahonri Schwalger, was a wheeling of their own, one which left viewers and participants alike in no doubt as to who would dominate the set piece from then on.
Tameifuna later scored the Chiefs' bonus point try when charging through the middle of a breakdown, a testament to his immense size, strength and self belief.
