The Grand Slam Special - What's That?

i saw odd drafting o this week, and it was called the grand slamy special. It was a cool special to have total points on sunday. A over under, minus one, 15 either way. Would bet that debel 11 dollars and 50 cents to win ten dollars. Har buna said, ah, but for the casual people that con it just like having fun throwing short money on their watch.
