EAST RUTHERFORD, N.J. — All the missing pieces — defense and a running game — are aligning at the right time for Eli Manning and the New York Giants. And just in time to play the Packers.

After routing the Atlanta Falcons 24-2 Sunday in the NFC wild-card game, the Giants head to Green Bay next weekend, a place where they will need all the help they can muster.

Manning carried the Giants (10-7) for much of the season, hoping the defense would get stingy, the pass rush would materialize and the running game would get on track. Now, all of that is happening.

“A great mix of run and pass and these guys have a great understanding of what our offense is,” Manning said of the help he’s receiving. “If we can get that run game going like we did in the second half, that opens up a lot of windows.”

And if the defense remains impenetrable, watch out.

“If we can play defense like that, we will continue to make ourselves heard in this tournament,” coach Tom Coughlin said.

Manning punctuated his best pro season by throwing for three touchdowns and scrambling for a 14-yard gain that woke up New York’s offense in its first postseason victory since its Super Bowl upset of undefeated New England four years ago. Next up is as big a challenge: the defending champion Packers (15-1), who won here 38-35 in December.

“We know they are a good team,” Manning said. “We played them tough here, did some good things here, we scored some points. We know offensively we are going to have to play strong, score some points.”

The team that couldn’t run the ball will be sprinting there, bringing along a defense the Packers actually might fear. Not to mention the passing offense led by Manning, who hooked up on a 72-yard catch and run by Hakeem Nicks in the third quarter that put away the inept Falcons (10-7). Manning also connected on a 4-yard TD with Nicks in the second period, and a 27-yard TD throw to Mario Manningham in the fourth quarter that finished it off.

The Giants’ last postseason trip to frigid Lambeau Field was a 23-20 overtime victory for the NFC championship two weeks before they upset the Patriots.

Saints 45, Lions 28

NEW ORLEANS — Drew Brees and the New Orleans Saints are pouring on the points, racking up the wins and rewriting the record books nearly every time they play.

Things sure are rollin’ on the river.

Brees led an unstoppable offense by throwing for 466 yards and three touchdowns, and New Orleans dominated the second half for a 45-28 NFC wild-card victory over the Detroit Lions on Saturday night.

New Orleans broke the postseason mark for total yards with 626, beating the record set 49 years ago.

“We were pulling out all the stops,” Brees said. “We play aggressive. We’re not going to apologize for that. That gives guys in the huddle a lot of confidence. We’re not going to pull the reins back. It’s pedal to the medal.”

Brees hit on 33 of 43 passes while throwing for the most yards in a regulation playoff game. He highlighted his night with three completions of at least 40 yards.

“We just focus on winning. We’re not focused on yards and records,” Saints coach Sean Payton said. “I’m serious when I say that.”

As usual, the quarterback had plenty of help from an offense that set an NFL record for yards from scrimmage this season (7,474), outgaining Detroit on the ground 167 yards to 32. The Saints (14-3) will travel to San Francisco (13-3) for next Saturday’s second-round game.

Matthew Stafford threw for 380 yards and three TDs for the Lions (10-7), who simply could not keep pace in their first playoff appearance since the 1999 season. They have lost seven straight postseason games.

“It’s a learning experience for the whole team. We’ll get better. We’ll be back,” Lions coach Jim Schwartz said. “Obviously it hurts right now.”

All-Pro receiver Calvin Johnson had 12 receptions for 211 yards and two touchdowns in his playoff debut for Detroit, but that was not nearly enough as the Saints’ defense responded in the fourth quarter with two interceptions by Jabari Greer.

Texans 31, Bengals 10

HOUSTON — Andre Johnson hugged his coach at the end of Houston’s first playoff victory — a moment a decade in the making.

“This is something not just for me, but for the whole organization,” the Texans star receiver said. “It’s a very special feeling. That’s probably the most I’ve smiled in a long time.”

As well he should.

Johnson, the face of this 10-year old franchise, scored on a 40-yard pass that powered the Texans to a 31-10 victory over the bungling Cincinnati Bengals on Saturday in an AFC wild-card game.

Johnson had plenty of help, too, from rookies J.J. Watt and T.J. Yates to running back Arian Foster’s two touchdowns and 153 yards.

Watt came through with a leaping interception return for a touchdown late in the first half, Yates threw a pinpoint pass to Johnson in the third quarter and Foster followed with his second touchdown — a 42-yard run in the fourth quarter — to finish off the Bengals (9-8).

Houston will play at Baltimore (12-4) next Sunday, a rematch of a regular-season game won by the Ravens.

“I’m just very proud of all the guys, and the job they did,” Texans coach Gary Kubiak said. “Hopefully, there are some more to come.”

The Bengals were in the playoffs for the third time in seven seasons, but haven’t advanced since beating the Houston Oilers following the 1990 season. They were done in this time by mistakes and a lack of pass protection.

“We have to get beyond this,” Bengals coach Marvin Lewis said. “We play in a very difficult division. We have to win games in the division, that is important and it sets up opportunities like this, all the time.”

Watt returned the first of rookie Andy Dalton’s three interceptions 29 yards for a score that broke a 10-all tie with 52 seconds left in the half. It sent the full house of 71,725 fans at Reliant Stadium into a frenzy, and the Texans into the locker room with all the momentum.

Dalton was 24 of 42 for 257 yards, while Yates was 11 of 20 for 159 yards in the first playoff game in the Super Bowl era matching two rookie quarterbacks. Foster’s first TD was an 8-yard run in the first quarter.
