Comparisons between Sir John Kirwan and Mark Hammett will reverberate as their Super 15 worlds collide this Saturday.
They are in the layer of New Zealand coaches working their way through the pitfalls and successes of professional rugby, men chasing the title which rookie coach Dave Rennie and the Chiefs annexed last season.
Debut head coach Kirwan has reshaped the Blues' playing roster as he looks for the starch which has been absent for too long. He'd like the progress, but not the player grief, that Hammett has achieved in his two years with the Hurricanes.
Three trial games have given Kirwan and his staff confidence they are on the right track and enough substance for selection debate before the Blues unveil their side.
Five-eighths, lock and the front row will occupy most of their discussion about the right mix for the Blues' initial display in their new world start at Wellington.
