...but it's not in our hands? We could win every game and not make the playoffs?
If Boston win all remaining games they should finish in at least 5th place as there are lots of clashes between the top 9 teams and points will be dropped elsewhere. However, it is an awful lot to ask any team to win every one of the final 8 games.
In this scenario it would be likely Hednesford and Chorley to miss out, with Barrow, Fylde, Guiseley and Tamworth making up the other top 5.
