FOXBOROUGH, Mass. – Shonn Greene placed the ball on the ground and used it as a pillow, resting his head on it after scoring the Jets final touchdown of a stunning upset.

A quiet climax to a very loud week of non-stop jabbering, poking, berating, and then some, mostly by the New Yorkers.

On Sunday, they proved that they weren’t all talk — trash talk — after all.

Now Rex Ryan’s rowdy bunch is headed to its second straight AFC championship game after New York backed up its coach’s boasts with a 28-21 win Sunday over the New England Patriots — the team with the best record in the NFL.

Mark Sanchez threw three touchdown passes and the Jets sacked Tom Brady five times in the most-hyped of the weekend’s four postseason games following a week of verbal potshots from both teams.

“Maybe everybody else never believed, but we believed,” Ryan said. “We’re moving on. Same old Jets, back to the AFC championship. The only difference is this time we plan on winning.”

In the end, Ryan was true to his exuberant self. He ran down the sideline and celebrated with his players after Greene’s 16-yard score with 1:41 left. And, when the game was over, Jets receiver Braylon Edwards did a backflip.

“We don’t care what people say or whether they like us,” cornerback Darrelle Revis said. “We just focus on what we need to do to win games.”

New York led its fierce rival 14-3 at halftime before Brady’s 2-yard touchdown pass to Alge Crumpler and Sammy Morris’ run for a 2-point conversion made it 14-11 late in the third quarter. But Sanchez came right back with a 7-yard scoring pass to Santonio Holmes and New York finished the upset with Greene’s touchdown.

The Jets (13-5) kept Ryan’s prediction of a Super Bowl appearance alive. The Patriots (14-3) lost their third straight postseason game.

The Jets lost last season to Indianapolis 30-17, but now have another chance for their first Super Bowl berth since 1969 when another loudmouth, “Broadway Joe” Namath, backed up his guarantee with a 16-7 win over the Baltimore Colts.

Ryan has said many times that the Jets are a Super Bowl-caliber team, and has irritated fans, opposing players and media with his bold remarks. Last week he said the game was a contest between him and Patriots Coach Bill Belichick. Then, after Antonio Cromartie called Brady an expletive on Tuesday, Ryan said he wouldn’t punish his cornerback.

Even after the game, the verbal shots kept coming.

“I’m not embarrassed. I’m just frustrated,” said Deion Branch, who scored the game’s last touchdown on a 13-yard pass with 24 seconds remaining. “The embarrassing part came from a few classless (Jets) guys after the game. There were a lot of classless things that went on after the game ended.”

Such as?

“Didn’t you see it?” he said. “You’ve got to go back and watch it. Pretty classless stuff.”.

When the game ended, Belichick walked slowly to midfield where he met Ryan, patted his conqueror on the back with his left hand and shared some words.

“We just didn’t do enough things well today,” Belichick said. “It’s obvious.”

Sanchez completed 16 of 25 passes for 194 yards and touchdowns to LaDainian Tomlinson, Edwards and Holmes. Brady, who played poorly for his second straight postseason game, was 29 for 45 for 299 yards, two TDs and one interception.

“Our expectations this season were very high,” Brady said. “Playoff football … comes down to who makes the plays, and we made too many mistakes.”

Now Sanchez gets a chance to beat one of the NFL’s best quarterbacks for the third straight week when he faces Ben Roethlisberger after knocking off Peyton Manning, who won the NFL’s last two MVP awards, and Brady, who is a favorite to win his second in four years.

“(Sanchez is) just now getting better and better and better,” Ryan said.

He wasn’t very good on Dec. 6 when the Patriots routed the Jets, 45-3. That didn’t matter Sunday.

“We don’t try to look back and try to fight history,” receiver Jerricho Cotchery said. “We play in that moment. That’s what it was all about today — making today our day. “

And the trash talk just keeps coming.

“Big Ben, he’s next on our list,” Edwards said. The Steelers have been made 3-point favorites.

In one of their worst halves of the season, the Patriots looked more like the ragged group that went 5-11 in Belichick’s first season in 2000 than the steamrolling machine that led the NFL this season with a 14-2 record and 32.4 points per game.

In the first two quarters, Brady absorbed three sacks and was sent scrambling at least that many times. He misfired on an interception on his first series after finishing the season with a league-record streak of 335 passes without a pick.

Then on the Patriots fifth possession, trailing just 7-3, they botched a fake punt attempt. Patrick Chung took the short snap and fumbled. He got the ball back but all escape routes closed. He was tackled at the Patriots 37 with 1:06 left.

Plenty of time for Sanchez.

Just one week earlier, Indianapolis had taken a 16-14 lead with 53 seconds left on Adam Vinatieri’s 50-yard field goal. But Sanchez brought New York back, connecting with Edwards on an 18-yard gain to the Colts 14, and Nick Folk kicked a 32-yard field goal as time expired, sending the Jets to Foxborough.

This time, after runs of 17 and 5 yards by Tomlinson and an incompletion, Sanchez hit Edwards for a 15-yard score and the Jets led 14-3 at halftime.

Fans had little to cheer about early in the game. The Patriots first series ended when David Harris intercepted the ball and ran 58 yards before a determined Crumpler finally caught up and tackled him at the Patriots 12. The Jets wasted the opportunity when Folk’s 30-yard field goal attempt went wide left.

New England settled for a 34-yard field goal by Shayne Graham and a 3-0 lead one play after Shaun Ellis sacked Brady for the second time on the series.

Sanchez was off-target early, overthrowing three open receivers on his first three possessions. After throwing a low incompletion on the next series, the second-year quarterback with the 4-1 postseason record finally found his range.
