Dante, week 1 and week 1a mean the first week and the OFFFICIAL first week. You know how next week I believe that we only have about 2-3 games, well that is week 1a in my view, then the next week, ALL teams play.
But guys, dont put too much thought in this "system." Of course it is a winning system, you are taking the underdog right?? If you bet the board every week by just taking the underdogs, then you will win about 58-60% by seasons end if you throw out the small dogs like +1-2.5. Problem is that the public takes the favorites, they never like the dogs
