Now the line has to change a decent amount for middling to work. Moving a half point or even a point doesn't create much of a middling opportunity. So if it ends up the line doesn't move or doesn't move as much as they thought it would, then they have just blindly bet on one side @ -EV (the vig). So if you are doing this middling thing you better be right about what you think the public is going to bet.
Of all the sports betting strategies, I think this is a tough one. Real slim, narrow edge if you are right, more often than not.
