NFL power rankings, 2021 post-Week 1 edition (previous rank in parentheses):
1. Buccaneers (1): Poor start by a defense that was the true Super Bowl 55 MVP. But when you've got QB Tom Brady and a cast of offensive skill players that could have served as the starting lineup in the 2017 Pro Bowl, OK for the D to take an early mulligan.
2. Chiefs (2): The re-engineered offensive line generally held up well – particularly given three players with zero NFL experience were debuting – as did Kansas City's proclivity to fall into double-digit holes before dramatically climbing out of them.
