NFL

Enough already! Let’s get it on!

And now, finally, a day like no other around here in the modern era of professional football.

The New York Football Giants, carrying all that tradition with them to the visiting locker room inside a stadium they no longer can call Giants Stadium, against the New York Jets, carrying all that heartbreak with them to the home locker room inside a stadium they share with the Giants, a stadium that can’t wait to embrace its Heartbreak Kids with a warm, green hug.

For lucky us, it is the perfect storm, a thunderclap of shoulder pads we get to witness just once every four years during the regular season, both teams desperate to keep their playoff dreams alive and to wear the crown of King of New York, and in that order.

Division title-or-bust for the New York Football Giants. Wild-card-or-bust for the New York Jets.

On Christmust Eve.

I’m picking the Giants.

JETS-GIANTS CHAT REWIND

UPDATES FROM OUR JETS BLOG

UPDATES FROM OUR GIANTS BLOG

After studying endless tape of both teams at my neighborhood Waffle House, I changed my mind.

I originally had picked the Jets, using the last tiebreaker known I could find: The Jets play well at MetLife Stadium; the Giants do not.

Then it struck me that coach Rex Ryan had made, in my opinion, a fatal error in judgment plastering a battered-and-soon-to-be-bloodied Eli Manning on the cover of Jets playbooks.

If the Giants have any pride, or pulse, they will get after Mark Sanchez the way Big Blue is supposed to get after the other quarterback, and they will keep Manning out of harm’s way.

Justin Tuck said he thinks he knows who will win.

“Giants,” he said. “That’s a question, a lot of people are going to say, ‘He’s guaranteeing a win.’ What do people expect me to say?”

Tuck, who dismisses Ryan’s trash talk that the Giants are now the Jets’ little brother, had not heard about the Manning photo until I told him about it.

“We have an opportunity to settle that too,” Tuck said.

Matt Slauson was asked why the Jets think they are better.

“Well, first off, we have a running game, that’s numero uno,” Slauson said. “When you play in December, you win by having a running game. As long as we put everything together, no matter who’s across from us, we’re going to dominate.”

It’s high stakes, high drama and high anxiety for all fans who bleed Jets green and Giants blue inside MetLife Stadium. It’s high noon at 1 o’clock Rumble Standard Time.

It’s the New York Football Giants, four years removed from their third Super Bowl championship, and it’s the New York Jets, 43 years removed from their first and only Super Bowl title.

It’s the New York Football Giants of Tom Coughlin, the old-school coach who needs his team to talk as loudly as it has all season when it begins to play the game. It’s the New York Jets of Rex Ryan, the carnival-barking rebel with a cause, the football Steinbrenner, loud and brash and outrageous, and the football Sinatra, doing it his way, even if no one ever has seen that way from an NFL head coach.

It’s Star Wars over a New Jersey stadium for all of New York-New York to see:

It’s Manning and Hakeem Nicks and Victor Cruz against Darrelle Revis and Antonio Cromartie.

It’s former disgraced Giants Super Bowl hero Plaxico Burress against Corey Webster.

It’s Jason Pierre-Paul against D’Brickashaw Ferguson and Tuck against Wayne Hunter.

It’s Santonio Holmes against Aaron Ross. “We like Plax and ‘Tone outside on their corners, [Jeremy] Kerley inside with their safeties and stuff, and I definitely like my chances against their safeties and linebackers,” Dustin Keller said.

It’s Ahmad Bradshaw and Brandon Jacobs seeking to out-Ground & Pound Shonn Greene.

“It’s going to be loud, it’s going to be tough for their offense, and our offense is going to be rolling,” Keller said. “It’s time.”

Giants to Jets: Let’s get it on.

Jets to Giants: Let’s get it on.

Let’s.
