As it always is, Week 1 was full of surprises that must cause us to rethink how we value many NFL teams, though some of those ratings were built upon assumptions of improved offensive play -- largely due to a supposed upgrade at QB -- that didn't come to pass. The Falcons offense looked as ineffective as ever in a home loss to the Steelers, then the Jets matched that energy while getting blown out by the 49ers on Monday. The Panthers offense appears as bad as it was last year, while the Broncos offense didn't take the expected step forward with its new QB. The No. 1 overall pick looked awful despite the Bears win, the Giants offense couldn't muster anything with Brian Daboll assuming play-calling duties and the Browns couldn't overcome several offensive line injuries to slow down the Cowboys pass rush even a little.

So what were the positives coming out of Week 1? The Chiefs and 49ers look as strong as ever despite not being fully whole on offense. The Texans held off a tough divisional opponent on the road with an awesome offensive performance. The Buccaneers' offense didn't take a step back at all after switching OCs in the offseason, though an impressive Week 1 could be discounted by the opponent. Ditto with the Vikings offense under Sam Darnold and the Stefon Diggs-less Bills against Arizona. Anthony Richardson showed it could be a fun Colts season if he can stay healthy, while Jameson Williams appears ready to give Lions opponents yet another option to worry about on offense. I've dived into the numbers and made my adjustments to my Week 1 spread power ratings, and I see a few games where I think the market is pretty far off the mark.
