Replacing your star halves with a no-name halfback and a second-rower would normally be widely questioned and have alarm bells ringing within club management. But this week, it is of no relevance other than highlighting fortitude.
Iro is a strong character and rarely flustered. Problems are met with a calculated response similar to that of Ivan Cleary, where you get what you see. There are no veils of secrecy with Iro and he is a matter-of-fact person. His pedigree in league is beyond reproach but as a coach, he has experienced more losing cultures than winning.
His time at the club has been under Tony Kemp and Cleary. Despite Cleary's 50 per cent win-loss record, it can't be said that the Warriors were consistent winners or had a winning culture.
Iro has seen the worst a club can dish up in terms of results, and pressure placed on the coach by fans, media and management, mostly in the past three months.
With that, Iro should have a good idea what not to do if he becomes a head coach. But what he really needs is to experience the highs of being in an environment that exemplifies effort resulting in winning attitudes.
The constant is winning, but the success is in the effort, as shown most recently by the Storm and the Sea Eagles and also culminating in eras like those of the Broncos, Raiders, Bulldogs and Eels.
Those organisations lasted beyond the one-year successes of the Tigers in 2005, Bulldogs in 2004 and Penrith in 2003. A one-off grand final appearance doesn't count either, as shown by the Knights in 2001, Warriors in 2002 and 2011, and Cowboys in 2005.
For Iro to succeed as Warriors coach, it can't be handed to him now.
He must tolerate playing the assistant some more before graduating from his apprenticeship, having endured all the pressures coaching staff must undergo to provide them with the tools to be successful.
