4th & Monday: Gronk's dirty hit, penalty flags in the stands and winning football in L.A.

Laugh all you want at attendance for the NFL games in L.A. But the city's two newly relocated franchises are trending toward each hosting playoff a game. 

While the Rams clinched their first winning record in 14 years, the Chargers have recovered from an 0-4 start to vault into a three-way tie atop the AFC West.

Check out the full NFL playoff picture. 

Nipping at the Rams' heels are the Seahawks, who knocked the Eagles from their perch atop the NFC with an impressive Sunday night win. The Rams and Seahawks square off in Week 15 in a game that will help decide the division. Before that game, however, the Rams host the Eagles.

The Chiefs' four-game slide has helped the Chargers and Raiders move into position for the division title, a development that would have been inconceivable just a few short weeks ago. The Chiefs host the Raiders in Week 14 and the Chargers in Week 15. Chiefs still control their own fate – if they can turn it around.

THE RUNDOWN

Titans 24, Texans 13: Houston dominated time of possession and controlled the field, but in the end couldn't stop another Marcus Mariota comeback win.

Vikings 14, Falcons 9: Minnesota handed Atlanta a serious reality check, grounding the Falcons' aerial attack.

Packers 26, Buccaneers 20: A 20-yard touchdown run in overtime gave the Packers a much-needed victory.

Dolphins 35, Broncos 9: Miami RB Kenyan Drake had himself a day, running all over Denver's vaunted defense.

Jets 38, Chiefs 31: Stop if you've heard this one before, but Kansas City unraveled late and the Chiefs' nosedive continues.

Jaguars 30, Colts 10: Blake Bortles loves playing the Colts. Jacksonville's QB briefly silenced his haters on Sunday, throwing for 309 yards and two touchdowns.

Ravens 44, Lions 20: Detroit's playoff hopes are on life support after a fourth-quarter Baltimore rout.

Chargers 19, Browns 10: San Diego kept the Browns winless, kept their own playoff hopes alive and kept performing in front of empty seats all in one game. But hey, Josh Gordon was back!

Raiders 24, Giants 17: Geno Smith isn't the Giants' answer, questions on Ben McAdoo's future linger, and Beast Mode rushed for 100 yards for the first time since coming out of retirement. 

Saints 31, Panthers 21: The Saints scorched the Panthers to take the sole possession of the NFC South division lead. 

Rams 32, Cardinals 16: Larry Fitzgerald moved to No. 4 on the all-time receiving list, but this one was all Rams, who clinched their first winning season in 14 years.

Seahawks 24, Eagles 10: The Seahawks might have shaken up both the NFC playoff chase and MVP race with this victory.

Cowboys 38, Redskins 14 (Thursday): No Ezekiel Elliott? No problem, says Dallas RB Alfred Morris, who ran all over the D.C. defense.

EYES ON THE (FANTASY) PRIZE

This was the final week of the regular season in most fantasy leagues, but some may still allow players to be added for the playoffs.

First off, Gronkowski owners will need a backup in the event of a suspension.

Also consider running backs returning from injury who could see more work down the stretch. The Packers’ Aaron Jones (20-yard TD run in overtime) and the Seahawks’ Mike Davis look healthy enough to cut into starters workloads.

Buccaneers running back Peyton Barber racked up 143 total yards in place of injured starter Doug Martin. He could be worth starting next week vs. Detroit if Martin's concussion lingers.

Speaking of layoffs, Browns wideout Josh Gordon was targeted 11 times in his first game action since 2014. He’s a high-risk, high-reward pickup for the playoffs.
