I think there is plenty of improvement in us. Frank Winterstein goes decent, he doesn't disappoint, he just doesn't do enough yet. Curtis Sironen has been a phenomenal signing and I am excited to see him get better. Every off season every club adds players, of which may or may not be off contract. We'll nab another quality, experienced forward and extra depth.
As for the backs, Taufua will return, who we've hugely missed since his injury. Kelly will likely retain his spot, unless we go for a quality back. And, if he doesn't show improvement after having another off season under his belt he will be replaced by Parker anyways, who is a tough, well balanced player. Parker will return from his ACL early next season.
I don't think Brown will remain, and we have some really good upcoming forwards coming through such as Paseka, Tanginoa and also Toafofoa Sipley, who has big raps on him from Warriors fans.
A majority of the players remain, so they will continue to develop together for the future, the future, in my opinion, that will only hold improvement. We have such a young, talented side and another off-season will strengthen these players not only physically, but mentally as well. I predict a top 4 finish in 2018
