So here's the deal - One book has NYJ +9(-123), and another has NE -7(-125). Is this a good opportunity? It sure seems like it, but maybe I'm missing something.
Here's what I came up with for potential outcome risking $100 on both sides. I don't know if it would be better to put a different amount on either side.
NE Wins by 10 or more
+$80 on NE, -$100 on NYJ = -$20
NE Wins by 9
+$80 on NE, Push on NYJ = +$80
NE Wins by 8
+$80 on NE, +$81.30 on NYJ = +$161.30
NE Wins by 7
Push on NE, +$81.30 on NYJ = +$81.30
NE Wins by 6 or less
-$100 on NE, +$81.30 on NYJ = -$18.70
What do you think?
