NFL power rankings: Nick’s picks for how teams stack up before Week 4

Brock Purdy and the 49ers are one of the hottest teams in football. Purdy went for 297 yards and four touchdowns against an inferior Cardinals team, who pushed the 49ers in the 36-30 game. Still, through all the injuries, the 49ers remain a top team in the NFL.

The Chiefs went into Miami and easily handled the Dolphins. Patrick Mahomes was efficient (20 of 24 for 246 yards with two touchdowns), and Rashee Rice finally got going with seven catches for 88 yards. Miami offered little resistance in the 24-10 win, and the Chiefs are one of the four undefeated teams that remain in the NFL.

Seattle goy Sam Darnold back from his hip injury, but Washington did an excellent job harrassing the Seahawks all game. Darnold finished with 379 passing yards and four touchdowns, but Marcus Mariota did enough to give the Commanders a 33-31 home victory.
