Your current situation reminds me alot of Wakefield. When Danny Brough left us we struggled to fill the gap and honestly couldn't compete with most sides without a recognised SH. Millward first and foremost needs to conclude whether Rangi Chase is staying or going. Once that's resolved the club can move forward.
It's hard enough competing with the top clubs, but to have your key man and influential player missing makes it impossible. Injuries on top of Ferres & McGoldrink leaving early has put more pressure on younger less experienced players which when out of form is rather hard to cope with.
Get rid of the deadwood or players who don't want to be there and rebuild
