Bodog had their lines at -15 for the past couple of days and now it's gone down to -14.5 with the option to buy a 1/2 point. Is this the time to invest or is it going to keep on going down? I'd feel a lot more confident if it was at -13.5 and the spread started at -14, but I don't understand why it would go anywhere but up rather than further down, if it opened at -15.
You don't buy half points on spreads this large. The hook can only even be considered if the spread is 3, and even then it's not worth it these days, they tax your ass too much for it.
Plus, you're on the wrong side. Seattle +15 is the play, or don't play it.
