After missing the postseason last year, the Buffalo Bills, Green Bay Packers, San Francisco 49ers are all 3-0, while the Detroit Lions are also undefeated at 2-0-1.

It’s only the fourth time since 1990—and the first time since 2013—that at least four teams have gone undefeated in the first three games of the season after not making the playoffs a year earlier.

The Bills won at home against the Cincinnati Bengals 21-17, while the Packers overcame the Denver Broncos 27-16 and the 49ers beat Pittsburgh 24-20, inflicting a third consecutive defeat on the Steelers.

Along with the Miami Dolphins and the New York Jets, Cincinnati, Denver and Pittsburgh are the only teams to have lost each of their opening games.

The Jets’ fortunes should improve once Sam Darnold recovers from a bout of mononucleosis, but their season is a good as over and the same applies to the Dolphins, Bengals and Steelers.

At the other end of the spectrum, the Kansas City Chiefs, New England Patriots, Los Angeles Rams and the Dallas Cowboys also improved to 3-0.

The Chiefs won the battle of high-octane offenses as they defeat the Baltimore Ravens 33-28 at home. Patrick Mahomes won the duel of second-year quarterbacks as he comprehensively outperformed Lamar Jackson.

Mahomes, the reigning NFL MVP, completed 27 of 37 passes, throwing for 374 yards and three touchdowns, while Jackson went 22 of 43 for 267 yards, adding 46 rushing yards and one score on the ground.

After a week during which the Antonio Brown saga dominated the headlines, the Patriots defeated the Jets 30-14, extending their winning streak over their AFC East rivals to seven games. Tom Brady finished with two touchdowns and 306 passing yards, surpassing Peyton Manning in second place for the most career games with at least 300 passing yards and two touchdowns.

Week 4 kicks off on Thursday night, with the Green Bay Packers playing their fourth consecutive home game this season as they host the Philadelphia Eagles.

The game is one of three primetime matchups, with the Dallas Cowboys traveling to New Orleans to face the Saints on Sunday Night Football and the Pittsburgh Steelers hosting AFC North rivals Cincinnati Bengals on Monday Night Football.
