I don't think the Jets played any better than the last time the teams met. The Pats just played that awful. Jets fans should enjoy this. They're not winning a championship.
I doubt that they can beat the Packers, but honestly I had some doubts that the Pats would if they made it that far. They can definitely beat the Steelers and the Bears, though, so a SB is definitely in play for the Jets.
And I'm with the OP: congrats to the Jets. One of the most discouraging trends over the past two years is that I still enjoy the Pats, but only because they're the Pats, in a lot of cases. 2001-2008 (not just the SB years, but also the few years that followed), it was a great time to be a Pats fan because, honestly, even if I hadn't been a Pats fan I'd be a Pats fans. Brady, Belichick, Seymour, Bruschi, Vrabel, McGinest, Faulk, Law... they embodied all of the things that I liked about football. Even in 2007, during and after SB42, they made it 99% of the way to perfection and went down swinging. 2005, 2006, and 2007 (and even 2008, I suppose) all ended badly, but I was proud of those teams even as they lost.
These last two years, though, the way that the season has ended has been a disgrace. The Pats have come up small on their home field, and been beaten decisively by teams that, for all of their thuggery and trash talk, flat-out wanted it more and beat us with pure physicality.
So yeah, I'm not even sure where I'm going with this (I'm really drunk), except to say that I'll always be a Pats fan because they're the Pats, but I'm rapidly approaching the point where I like and support them more because of the logo than anything else. They don't embody the philosophy or mentality that I admire in teams anymore, and while that's kinda disappointing, it also kinda just makes me appreciate the last decade more. Just goes to show how lucky we were to watch those teams, and how apparently unsustainable it was.
On a side note, these Jets would be an extremely likable team if they didn't talk so damn much. But they do, so they're not. Oh well.
