No shit Raiders. If a book tells you a line, that's what it is. I saw the line and took it. You never agreed to the adjusted line last week. That's right it won, but yes it does matter. You never agreed to the adjusted price and therefore you had no acton then and need to take 100 off your total.
If I am dealt the line you stated, then I will either have to accept it or so the bet is no action. You never accepted anything last week.
