Griffin said last week time and money had been invested in young players at the club and a decision was made not to recruit outside.
“So we have to win with this group, and the sooner we do that the better,” he said.
“We’re demanding of them and we’ve got high expectations of them.”
White said he backed Griffin’s commitment to the squad, which will be led by Sam Thaiday next year.
Griffin said yesterday a lot had been said about the younger Broncos but he could not say enough about the older brigade – such as Lockyer, Thaiday, Corey Parker, Justin Hodges, Peter Wallace and Ben Hannant.
