Odds are not bad. I'm predicting the following prior to the last day of the season.
Boston to win the next 3.
Bradford to win their next 4
Guiseley to win just 2 of their next 4 and lose the other two.
So going into the last day it will be
BPA 79
Guiseley 79
Boston 76
I'd expect both BPA and Guiseley to win there last game and Boston lose narrowly to Marine.
So BPA to win the title, I think 11/2 is very generous.
