I'm tempted to say something snarky like, "We're on to Washington," but instead I'll say that 4--0 is better than last year's 1--2/2--2 and that ended up OK, despite leaving them with a big hill to climb and some scary days in December.
Most importantly, no one knows what this team will be in December, other than one of the teams playing meaningful games. BB and Josh seem to be able to reinvent the team every week, so January is an eternity in the future.
The big pluses are obvious: the D is awesome and the Pats still have the GOAT at QB. Gostkowski's departure is a huge unknown, otherwise I'd say STs were another big plus. The Offense, as it does every season, won't find its Playoff identity until, well...um, the Playoffs, but there are too many weapons for it not to be strong.
Add the usual question mark about "injuries," and that's all I've got at this point.
