It's not that hard at all, though you can choose to look at it any way you like.
They have not played the Dolphins yet. That makes it, by definition, too early to claim they are 2-5 and 0-3 in the division. The Dolphins are solid this year, but are not the 1972 version of their team. This Bills team has a lot of talent and potential, and has been in every game this year. If they can pull it together, they can certainly win in Miami. If they do, the season can turn around.
That is an example of the use of the subjunctive in the service of positive thinking.
