Ross, you forgot about last year so soon? We were +3 at home vs. Tennessee. Otherwise you're right, it goes WAY back.
I didn't have my best NFL season last year but it did get off to a good start. After watching the preseason I challenged us to score 17 points by wagering seperately on Tennessee and under. The total was 37 so that made the projection 20-17 Tennessee.
Anyone who is new to this, that's a good method. Take the spread and total and look at what they are projecting and see where you think it errs, if at all. So in this year's opener at +4 and 38.5, that is essentially saying the score will be Denver 21, Miami 17. If you think we will definitely score more than 17 points, you might bet Miami and over seperately. As long as we score 17 points or more, no way you can lose both bets.
As far as the vig, that's the bookie cut. Called vigorish. The -110 on each side and not even money. The poster who complained about monkeying with the vig probably means they frequently move to -120 on one side and even money on the other side, or perhaps beyond that. I acually like places like that, because it means they are overreacting and half the time it will be in your favor.
