This bit is the essence of long term success IMO.
To be successful over a long period of time teams have to be rebuilt and after Bennett had been in charge at Brisbane for a few years he knew he had to make some changes.
His side steadily improved after their debut season in 1988 but did not win their first premiership until 1992 - and by that stage Bennett had remodelled his team.
"I had to acknowledge how to sustain this, how to stay ultra competitive," he says. "I studied other clubs and saw how they made mistakes; they had been great but held on to players for too long."
Bennett reckons he built five different teams at the Broncos, learning how to strike the balance between retaining ageing players and talented youngsters coming through.
"You have a 20-year-old who is not as good as your 30-year-old pro but you know that he is going to be, he has got all the right attributes, so you take a short-term loss for a long-term gain," said Bennett.
