I think it's difficult to be all things, especially with such an enforced transition mid-season. We've had to make a running game work, and quickly, and on the hoof. And it's worked. And now the passing game is suffering a bit. But we can work all this through, one game at a time, we've shown it already. We can't give up on this Bills team, mainly because they keep identifying their weaknesses (for the most part) and overcoming them as they go.
After we win the superbowl, we'll probably be ready for the playoffs.
