The reason I believe this is because rex ryan will not be conservative offensively and this could turn into a colts by 10+ victory. (IE Like rex did last week on 4th and 1 at the end of the game. Rex is playing to win so I believe taking +8.5 is not a good bet. I would prefer jets punters to back them on the ml if you're considering a jets side.
I believe if the jets are losing by 7+, any 4th and short close to midfield he will be going for.
