Coach Ken Hinkley said the club was only just beginning to see the best of Lobbe.
"He is at that age where ruckmen tend to develop best," Hinkley said on Monday.
"He has had an outstanding season for us this year despite having to shoulder a lot of the ruck on his own."
This last sentence might suggest Redden and Lobbe will play together next year.
