I'm hoping that decisions made for next season are done early, so the new squad can have a proper preseason together. I would keep the core of this squad but replace those leaving with local players and/or those with experience. This is what I'd do:
Give Gibson a 1 year contract as player/manager.
Offer contract (in order of how much I'd want them to sign): Connelly, Rae, East, McGrory, Fitzpatrick, Cooper, Roy, Nditi
Transfer options: Gavin Reilly, Aaron Muirhead, Owen Moxon, Tommy Goss, Kyle Jacobs, Dan Pybus
I would also try to sign O'Connor if released but expect he'll be given a new contract.
