What We Learned From Week 17 in the N.F.L.

Chargers 34, Broncos 13: After Broncos Coach Vic Fangio inexplicably settled for a field-goal attempt to take 3 points out of a 20-3 deficit in the fourth quarter, the Chargers quickly ended the affair. Andre Roberts returned the ensuing kick 101 yards for a touchdown, and Los Angeles will now face Las Vegas in Week 18 with a playoff berth on the line. The last time the two teams played, a Week 4 Chargers win, defensive end Joey Bosa questioned Raiders quarterback Derek Carr’s ability to face pressure.

Eagles 20, Washington Football Team 16: It was easy to mock Eagles Coach Nick Sirianni in the spring when he said he had played rock paper scissors with draft prospects to gauge their competitiveness. Nobody’s mocking him anymore. After a 2-5 start, Sirianni pivoted Philadelphia to rely more on the run and now, at 9-7, Philadelphia is on the verge of making the playoffs. Cornerback Rodney McLeod supplied the game-sealing interception of Taylor Heinicke in the end zone.

Rams 20, Ravens 19: This win showed why the Rams traded for Odell Beckham Jr. On fourth-and-5 from the Ravens’ 12-yard line, with 1:08 left, Beckham hauled in an extremely difficult 5-yard reception. Matthew Stafford, who had been intercepted twice on Sunday, went back to the receiver for a 7-yard touchdown pass on the next play.

Bills 29, Falcons 15: Josh Allen’s three interceptions gave the Bills a scare but the re-emergence of running back Devin Singletary helped push Buffalo to the win. Last season, the Bills showed zero desire to run the ball in January, even calling 20 consecutive pass plays to open up the divisional playoff game against Baltimore. With so many opposing defenses focused on stopping Allen, Singletary, who shredded the Falcons for 110 yards and two touchdowns on 23 carries, could provide much-needed balance.

Patriots 50, Jaguars 10: The rookie quarterback Mac Jones got back on track by going 22 of 30 for 227 yards with three touchdowns and no interceptions. Of course, in New England, it all starts with the run. Damien Harris and Rhamondre Stevenson, who combined for 142 yards, helped create opportunities for Jones to throw successfully.

Raiders 23, Colts 20: Receiver Hunter Renfrow made the play of the game, selling out for a 24-yard reception on third-and-10 with 54 seconds left to set up a game-winning field goal.
