<"Obviously we are very pleased to have all three players back on board with the Broncos," said Mr Cullen.
<"Both Ben (21) and David (22) are virtually just at the start of their NRL careers and we see them as being the leaders of the next group of young players coming through. And Michael, who is also only 22, has expressed his interest in being a long-term player with the Broncos.
<"This time of the year can be difficult for all concerned when new contracts are being negotiated, and it is always a relief when both parties agree to terms."
<"There are still a few with whom we are to come to terms, but I expect to have a clean slate within a week or so," Mr Cullen revealed.
