I wouldn't bet this game because the score will likely be too high. I hate betting high scoring games because they can be very close, equal games & the favorite end up covering with a late score.
That being said, I do find it interesting that the line keeps dropping. Started at 12 and is down to 8.5 at some places.
Any chance this is a low scoring game? If so, how?
