Stranded I would say this summer is the last chance for Moore to make a decent move i.e. to a decent Championship side, so he may well be inclined to make it happen.
If he stays and essentially sits out a year then the options for a then 30 yo CB with known injury issues will be limited even as a free transfer.
Question remains if we could afford to not select him next year if we are unable to move him on. Having 35k pw (or whatever it actually is) not playing is wasting a massive chunk of our available budget.
If we can't move him on, we may as well use him. For all of his criticisms, he obviously isn't a bad player when he plays well, or even when he's just average, he's still a good player at this level.
We have to move him on simply because of what he costs. If his wages were a third-ish of what he is earning, I'd be wanting to keep hold of him for sure. It's just unfortunate for him our situation is such where we can't really afford to keep him on.
