No lead was safe on Sunday, with several teams engineering huge second-half comebacks (yes, the Falcons collapsed again). There was a little of everything — there was even a tie! — and a week that was expected to be an appetizer for Monday night’s matchup between Kansas City and Baltimore proved to have plenty of its own entertainment value.

Here’s what we learned:

One* Sentence About Sunday’s Games

*Except when it takes more.

Seahawks 38, Cowboys 31 Dak Prescott kept up with Russell Wilson for nearly the entire game, throwing for 472 yards — his second straight game with 450 or more yards passing — and three touchdowns, but after getting Dallas as close as the Seattle 22-yard line on his team’s final possession, he scrambled around before throwing an interception in the end zone that cost his team a potential upset.

Bills 35, Rams 32 Los Angeles controlled the time of possession, had a 103-yard advantage in total yards, took all the second-half momentum as they erased a 28-3 deficit, and then they lost. Maybe this season isn’t so different from last season for the Rams, who seem to have used up all their good luck during the 2018 regular season.

Patriots 36, Raiders 20 New England ran what amounted to a modified version of the Air Raid offense during Tom Brady’s best seasons, but the Patriots are loving running the ball thus far in the Cam Newton era, with 250 rushing yards on Sunday — the second time they have gone over 200 this season. They dedicated the run-heavy win to running back James White, who missed a second consecutive game after the death of his father.

Steelers 28, Texans 21 At halftime in Pittsburgh it looked like an upset could be brewing, with Deshaun Watson having no trouble scoring against the Steelers’ vaunted defense. In the second half, Houston managed just 51 yards and two first downs.

Titans 31, Vikings 30 Derrick Henry chewing up yardage, Ryan Tannehill finding room to work downfield, Tennessee’s defense looking absolutely useless and Stephen Gostkowski trotting onto the field in the final two minutes to win the game with a field goal. It’s a bit like “Groundhog Day,” but it’s also a recipe that has worked just fine for the Titans in all three games this season.

Buccaneers 28, Broncos 10 There wasn’t much hope for a decent game once Denver starting quarterback Drew Lock was injured last week — his backup, Jeff Driskel, was pulled in the second half, leading to snaps for third-stringer Brett Rypien — but a turn-back-the-clock game from Tom Brady made it a laugher. That Brady looked young again in a game in which Rob Gronkowski seemed to shake off the rust was likely not a coincidence.

Colts 36, Jets 7 Philip Rivers joined Drew Brees (550), Tom Brady (547), Peyton Manning (539), Brett Favre (508) and Dan Marino (420) as the only players in N.F.L. history with 400 or more career passing touchdowns.

49ers 36, Giants 9 The most interesting aspect of a game in which San Francisco’s practice squad embarrassed the Giants’ starters in New Jersey was the fact that it was a Scorigami, i.e., it was the first time this score has happened in a game — the 1,056th unique score in N.F.L. history.

Bears 30, Falcons 26 Mitchell Trubisky somewhat surprisingly beat out Nick Foles for the starting quarterback job to start the season, but that experiment is likely over, as Trubisky was pulled for ineffectiveness against Atlanta, and Foles engineered a thrilling comeback with three touchdown passes in the fourth quarter. For Atlanta, a second straight week with an epic collapse could have Coach Dan Quinn on the hot seat.

Panthers 21, Chargers 16 Despite playing without running back Christian McCaffrey, Carolina won for the first time since Week 9 of last season, ending a 10-game losing streak. And while Justin Herbert lost again, the rookie threw for 330 yards, becoming just the fifth player to have 300 or more in each of his first two starts.

Browns 34, Footballers 20 Washington kept things fairly close for three quarters, but Cleveland asserted itself in the fourth, Nick Chubb continued to thrive and the Browns (2-1) have a winning record for the first time since 2014.

Bengals 23, Eagles 23 (overtime) A 59-yard field goal is hardly a gimme, but Matt Pryor, a Philadelphia guard, has to be blaming himself for his team’s failure to win after his false start late in overtime took away Jake Elliott’s chance at hitting what would have been a game-winner.
