If he smashes it, we have our permanent manager.
If he rescues us and has a decent season, we are in a better position to hire a long term manager because its in the offseason and the new man could immediately have a transfer window and hopefully we will have finished in a reasonable enough position/made a few signings that make us an attractive landing spot. Plus, Unsworth then has a decent managerial spell under his belt that he could take to another club (Please!)
If we continue to struggle/look relegation material, then we'll be less excited and maybe need to look at a survival specialist in January or February.
Seriously, in this league, 50 points will keep us safe by a mile and would probably mean that we are 8th or 9th in the league.... Just get us 50 points.
