Dallas - 4 means that if you bet on Dallas, they have to win by 4 or more. We are paying out ties this year.
So the -4 automatically gives Miami four points. Just like Miami +4 automatically gives miami 4 points
Basically the score right now is 4-0 Miami.
So If Dallas wins 25-20, then you would add the 4 points that Miami is getting from the spread and Dallas would cover.
Got it?
