SA is solid midfielder who can fill in anywhere across the middle and he chips in with a few goals here and there, Hendrick would be out the door before SA. If Scotty goes then we can only realistically replace him with a young up and coming talent either that or we would be seeing one of SD4 JC JBG or RB/AL dropping to the bench as a squad player and I don't know about anybody else but to drop one of those to a squad filler role would take somebody with considerable talent coming in.
Marney Vokes & Hendrick are all ahead of Arfield when it comes to who I would let go
