Why impossible?
Saints can still in theory get 90 points.
It will most likely take around 76 points to get 6th spot.
The current Saints squad shouldn't really drop more than the 14 points in the next 19 games against the teams in League One.
Charlton are too far away already to be caught by Saints. I doubt Colchester will be caught either. Saints are basically going for the final playoff spot or possibly 5th.
Well it was never going to happen in a million years anyway. Imagine the outrage if council tax money was used to help Saints. Not every council tax payer is a fan of the local club.
