You can build around those. Graham and Zyro too if they come back strongly. Iorfa if he can get back to his best (needs to happen soon, mind). Gibbs-White, Wilson, Ennis, Herc and Johnson might have a part to play but they are still developing. I don't subscribe to the ham fisted theory of sending players out on loan en masse as if that solves anything but Bright genuinely does need to go out for at least six months and then he might have something to offer.
The rest are at absolute best, squad players and not even integral ones - you could tolerate having Edwards around for his attitude for instance, you could accept that Coady has a year left on his deal, we won't be able to sell him and he'll be ok as a second or third choice right back that we use when absolutely necessary. Fine, but you don't want either starting much more than 10 games. They're automatic choices right now. When you go right through the team and in practically every area - other than out wide when everyone's fit - there are glaring weaknesses and players that have no business even being at a club like this then it underlines the scale of what needs to be done. Even promotion winning teams occasionally carry the odd weak link because they fit their system. We have tons of weak links who don't fit anything.
I seem to post this kind of list a lot, but at present I wouldn't lose any sleep at all if all of the following went in the summer, I've got very little time for most of them and the odd exception such as Silvio - who if he'd stayed fit and we'd actually used him, might have been ok - are just collateral damage because we genuinely do need to more or less start again:
Saville, Silvio, Deslandes, Randall, Upton, Rainey, Hayden, O'Hanlon, Reid, Simpson, Williamson, Borthwick-Jackson, Stearman, Nazon, Wallace, Coady, Price, Henry, Collins, Lonergan, Doherty, Mason, Bodvarsson, Gladon, Edwards, Oniangue, Saiss, Batth, Ikeme, Ebanks-Landell, Dicko, Evans.
THIRTY TWO players there and hardly any of them are anything like fit for purpose for a top six side. Now of course you're not going to get rid of all of them; you can only sell what people will buy for a start. And ok, it includes a fair few kids who've never really got near a first team spot for us. But still. If you need an illustration of the scale of the task at hand this summer, run through that list yourself and try to convince yourself that we might be alright if any of them play 30+ games next season. Good luck with that one.
