You would have a much greater likelihood of hitting the middle if it was for the entire game.
The fact that it is for the second Quarter only actually makes it less likely because you need numerous scores.
Sure, you could hit on Miami 3-0 where you get a win and a puch, but the 7-6 0r 14-12 isnt very likely.
It would be more likely to get something like 34-32 for the whole game or 24-23, etc.
