I think that what's important to note is that this isn't really a "moral" victory in the sense that we saw some nice things about our team, we played hard, and "we're almost there!" It's a true moral victory in that this team is demonstrating that they WILL win, if they learn to clean up mistakes.
This isn't a team that was 3-0 because they were playing above themselves and got brought down to earth by a good team. This is a team that won 3 games because they're good, and lost a game to a good team because they played poorly. Gone are the days of flukey wins and losses. We're not going to see those crazy, inexplicable performances that we're so accustomed to anymore. No more wins because Fitz played out of his mind, or losses because we were figured out. This is not territory that us, as Bills fans, are used to. We haven't seen a good team like this since Flutie replaced Johnson.
I've found myself no longer hoping to get to the next step, but waiting for us to get rolling. Just like in the Jets game, yesterday, it was only a matter of time before the offense started moving, and when they did, even Belichick was having trouble with them. This team is going to clean up their mistakes, and they're going to be hard to stop.
