Giantfandave- Most likely when you post your play, and they figure out their mistake, all plays will be off. The same thing happened to me last year. I wanted Utah St. -11 in a CBB game and when I called it in they repeated my play back to me @ Utah St. +11. I called back and asked if they were sure on the line and they said they were, so I put another dime on it. When they figured out the mistake and called it a no play, I told them that I wanted the bet @ -11 (Ut. State won by 16) so they gave me the win. You have nothing to lose, go LARGE on the under.
