Those with an interest in Blues rugby and mathematics would have been heartened by the sequence which unfolded at Eden Park.
As the lineout and scrum regained some solidity, the Blues' defensive systems showed an equally healthy dose of redemption.
It was about time. Since the timid opening Super rugby loss against the Highlanders, sides have opened up the Blues in a chain of try-scoring concessions which yielded 4, 3, 4, 3 and 3 tries.
Not pretty at all and the sort of detail which would have agitated Graham Henry, who is in charge of the defensive strategy, and Grant Doorey, who also works with the defensive systems.
Henry worked at the apex of world rugby with the All Blacks where strong defence was not negotiable. It was demanded and expected just as Doorey learned when he played in the NRL before coaching.
