I don't think it will happen, but I've got too much time on my hands this afternoon and I was bored, so I thought I'd look at the figures.
There has been a few mentions of our promotion run in 2007-08. It was mentioned again on BBC RC last night that we gained promotion from a similar position under D&D. The managerial change that season was much earlier, just after we played Bournemouth in the 2nd round of the FA Cup. I don't recall us actually being bottom at the time either, though I could be wrong on that. Just looking at the figures it is mathematically possible.
We have 19 games left or 57 points to play for, we currently have 25 points so a maximum possible of 82. We have collected 13 points from our last 5 games. If that form is maintained we would likely achieve 76 points (assuming last for games are all wins), that of course would give us a new record unbeaten run.
Recent Conference North play-off promotions...
2012-13 5th Halifax 75 Promoted
2011-12 5th Nuneaton 72 Promoted
2010-11 5th Guiseley 73 (2nd place Telford promoted)
2009-10 5th Droylesden 64 (2nd place Fleetwood promoted)
2008-09 5th Southport 76 (2nd place Gateshead promoted)
2007-08 5th Barrow 76 Promoted
It is possible but we would definitely need another very long undefeated run.
