Bosch made the most of front-foot ball to keep their team in the right areas of the field and the Crusaders backpedalling.
Regardless of what happens in the Sharks’ tour finale against the Chiefs in Hamilton this week, the successes against the Waratahs and Crusaders have shown that the Sharks can beat the competition’s best when they have the correct focus and the right players in the right positions.
On Friday in Christchurch the Sharks were imperious for long periods as their pack dominated and Curwin Bosch did the rest as the flyhalf general.
It looked relatively easy for the visitors against the nine-time champions as halfbacks Louis Schreuder and Bosch made the most of front-foot ball to keep their team in the right areas of the field and the Crusaders backpedalling.
Territory was dominated, penalties were forced and Bosch kicked the goals, seven of them in total. It was reminiscent of how the Springboks beat the All Blacks in Wellington last year and it is the best approach to stealing wins in New Zealand.
Bok coach Rassie Erasmus would surely have noted the composure Bosch has shown in his two starts on tour since the benching of Robert du Preez following the home defeats to the Jaguares and Reds.
Bosch has been in the Bok wilderness since playing fullback in the defeat to Wales in Washington DC last June, and a lot of that will be down to the lack of opportunities he has had at the Sharks in his preferred position of flyhalf.
Nobody is suggesting that the 21-year-old is challenging Handré Pollard, but Bosch is surely proving that he is worthy of a place in a greater Bok squad given that he can cover No 15 and 10, and is a gifted goal kicker.
