East Rutherford, N.J.

All the momentum the Los Angeles Chargers gained in their playoff push came to a screeching halt last Saturday.

Their four-game winning streak ended with a clunker in Kansas City.

Now they're in must-win mode again, starting this weekend against the New York Jets.

"I don't know that there are doubts, it's just your natural emotions," Chargers quarterback Philip Rivers said. "You're just going, 'What has happened? ... Is this all, come falling down?' So, some of it is just your emotions in the heat of the season and where we were."

The Chargers (7-7) are still in the middle of the AFC playoff mix, but their margin for error has disappeared. Los Angeles, which lost to the Chiefs 30-13, needs to win each of its last two games — at MetLife Stadium on Sunday and home against Oakland next week — and get lots of help elsewhere.

"We can't let one hiccup last week cause us to tank or do anything crazy," Rivers said. "We just have to take care of our business."

They've done it before.

In 2013, the Chargers had the same record and faced the same playoff predicament. They won their last two, got some help from other teams losing and completed an unlikely run to the postseason.

"A couple of us who were here said it kind of feels like that again," Rivers said.

Meanwhile, the Jets (5-9) saw their playoff hopes end with a 31-19 loss at New Orleans last Sunday.

Now they're hoping to play the role of spoiler while looking to end the season on a positive note.

"I feel like we are getting closer," cornerback Morris Claiborne said. "As long as we keep preparing and fighting the way we've been fighting, it's going to eventually come together for us."

The Chargers can still win the AFC West, but need the Chiefs to lose both of their final two games: home vs. Miami and at Denver.

That might be the most clear-cut of the possibilities for Los Angeles, but maybe the most unlikely. A wild-card spot might be the way in, but the Chargers also would need Tennessee (8-6) to lose at home to both the Rams and Jacksonville because the Titans would hold a tiebreaker at 9-7.

Los Angeles also has Baltimore (8-6) and Buffalo (8-6) standing in the way. The Ravens finish with home games against Indianapolis and Cincinnati, while the Bills are at New England and Miami.

"All the scenarios out there, we're aware of and they all include us having to win," Rivers said. "That's the focus, just find a way to win this game in New York and then we'll worry about Oakland."
