"I've been doing this for a long time," he added, but much of that time has been in rugby backwaters compared with the upper echelons of New Zealand rugby. The macho bravado was most odd, the "men need to stand up - so bring it on" line.
This is for an excitable moment before a season or big game, not after your team played like bozos. Puffing out the chest following a humiliating loss is what a Will Ferrell character would do in a Hollywood spoof.
Self-deprecating wit would be better than boasting "I'm going to be here for a long time".
If Kirwan fluffs those lines, how does he get messages across to players? Not well, is the guess. Players respond to coaches who they feel are on their side - think Wayne Smith - rather than on a personal mission.
The Blues aren't playing as if they are on the same page as a coach who is "confident I'm the right man for the job".
Outrageous success came quickly to Kirwan the player, and he skipped the ground-up approach of coaching club and provincial rugby. He won't have learned much in charge of Japan and Italy relevant to the far superior arena of New Zealand's national game. He has little substance to fall back on.
His term is all but over.
