Listening to the Athletic NFL show, they said the Hutchinson injury just puts them into the top category as Super Bowl favorites, as opposed to possibly being their own category above everyone else.
They are saying what happened this year was that the defense was legit good. But the defense was legit low mid last year, so even if they fall back to that now; they still like this offense better. Their one caveat is that they think the offense is slightly thinner this year, so they can't take injuries on that side of the ball, but as is. This is probably a better offense than last year, and at worst a similar defense, just with a worse front, and better back. And possibly still a slightly better defense than last year. Just not a clearly better defense like they would be with Hutch.
