Former New Zealand Warriors coach Matt Elliott believes the club's environment has a negative effect on its players.
Elliott, who was in charge at Mount Smart for 29 games from 2013-2014, told Radio Sport's D'Arcy Waldegrave that the Warriors have wasted the talents of several good players over the years.
"Bad players go to the Melbourne Storm and turn into good players. I see good players go to the Warriors, and get worse," said Elliott.
"That isn't about their ability, that isn't about the quality of the person, it's about the environment, and the environment needs to change. Changing the environment is awkward, and you're going to have to go through resistance. That's wasn't something that in my experience there, that was embraced."
Elliott believes there needs to be a complete change in the whole approach of the Warriors organisation.
