Hoffman hit back at rumours of lackadaisical attitudes to training and a lack of professionalism that have dogged the franchise in recent years.
"Trust me, we train hard enough," he said.
"It's just at the moment we don't have blokes that are first-grade ready.
"That comes through the development and that sort of stuff. You can't be training players to be first-graders in first-grade.
"I think Steve's identified that, that there needs to be some improvement in the development of the juniors. They've won three 20s grand finals but we've got to make sure they're turning into first-graders."
He said he did not regret any of his time at the Warriors, which included one season as captain.
"It's a season of unfulfilled potential, I could argue we've had three years of that," Hoffman said.
Hoffman's future is uncertain and said he expected to make an announcement next week.
He is being courted by his former club Melbourne and has offers from several NRL and Super League clubs on the table, with the 33-year-old saying he would definitely play on in 2018.
"I'm pulling the boots on next year, don't you worry," he said.
