I see what you're saying, but (and I admit there are a lot of 'ifs' to come) if we stay up, we are more likely to get a good investor who will put some money into the club. It seems there is plenty interest, and we can hope that is interest from the 'right' sort of buyer who wants to progress the club.
That being the case, we may not lose as many of our best players as you think, so long as the deal is done in a reasonable timeframe, which appears to be possible judging by the progress the administrators are currently reporting.
Given what we've seen in the last third of the season, things look to have 'clicked' and we're playing good football and winning games. If we keep the majority of the squad together and keep up the momentum, I don't think we'd go down next year, even with a 12 point deduction... like I said, there's a lot of ifs in there, but I don't think any of them are impossible from what we're seeing on the pitch. It's all a case of keeping the squad together as much as possible, and a new owner would be foolish to allow the squad to be decimated judging by our recent performances. You'd rightly expect that they'd hang on to as many of the first team as is humanly possible, and if they can be onboard by the end of August, that's far from an unreasonable expectation, provided the new owner has the resources and is willing to invest.
