I don't think Reed staying or going has any relevance to whether he gets any game time in the last few games, keeping him and loaning him out to get regular football is probably the most likely outcome, but whatever Wilder's decision, giving him a run-out at MK Dons is unlikely to make any difference.
Are there any decisions to make on most of those really?
EEL is a Wolves player who hasn't been great for the second half of the season.
O'Shea has already had plenty of chances to show what he can do, but he's already just backup a division lower than where we'll be.
Long will never be our first choice keeper.
Done is a striker who rarely scores and a disaster defensively, but the manager likes him.
Nothing that any of them could do in the last three games will change their futures. EEL is probably going back to Wolves anyway, the others would be back-up at best, Done and O'Shea both played and scored the other day, but it's unlikely to make any difference to the decision about them staying or going.
