Let me share some Daily Telegraph type explosive Journalism.
It was Flanno that told the Board there were no concerns within the supplement program. He told them that he (Dank) was employed only to provide guidance on the GPS system for the HPU. No involvement with supplements.
On the basis of that information from the Head Coach and to clear the Clubs name, the Board were open and transparent with the NRL and ASADA, hence the internal investigation.
Unfortunately, Flanno changed his story AFTER the Club proceeded with the internal investigation.
This should answer the perception of WHY the Club would self audit.
