We still don't know what division we're in next season, but either way, I think it would be unrealistic to think that we'll see a total clear-out of the squad (no idea, tbh, what will happen with the manager).
A number of us have said, quite rightly, that the likes of Nesbitt (to take maybe the most commonly discussed example) has flattered to deceive and should get a 'thanks and goodbye'... along with the vast majority of the other unsigned players.
Two problems with that: a. we don't know what any individual player earns; b. we can judge what we see... but there's no way to 'judge' the player we might sign to replace him (see also a. money). If it was a case of 'would you rather player x than Nesbitt', you can make a judgement; but 'bin Nesbitt and see what we get' is too easy.
MCT (and whoever is manager) won't be making moral judgements ('he deserves to be punted'), but practical assessments of what we can get. And they'll be doing that to a very tight time-scale.
So I'd be looking to retain maybe eight of the current squad immediately after the play-off final, regardless of which way it goes... then trying to sign another eight who are better than what we have (then adding a couple of loans and integrating two or three boys). Easier said than done, of course, if we go down...
In addition to Strapp and Lyon (who have signed, although Strapp might disappear), the other six for me would be: McAdams (obvs), Ledger, Fjortoft, Jacobs (c), Nesbitt, McGuffie. I'd pause over Oliver and Colville if we're in League One, but that's it.
