Brandon Jacobs plays for teammates

NEW YORK -- The boos Brandon Jacobs heard at MetLife Stadium on Sunday didn't bother him. The only opinions that matter, Jacobs insists, are those that come from inside the New York Giants locker room.

"I'm playing for my teammates, my brothers," Jacobs said on Tuesday. "That's who I care about. I don't care about anybody else to be honest with you. I don't care if [fans] cheer for me another day. They could boo me every day. But they should boo when I'm about to score these touchdowns."

Leading up to the game, stories came out in which Jacobs said he didn't think the Giants were using him correctly and he believed he wouldn't finish his career with New York. That led to fans turning on him.

Speaking at an NFL Play 60 event in a Brooklyn middle school Tuesday, Jacobs vowed to refocus his efforts over the final nine games of the Giants' regular season.

"You're going to see a change, man. You're going to see a change," Jacobs said.

Jacobs said conversations with his wife, Kimberly, and teammates such as Deon Grant and Antrel Rolle after Sunday's game convinced him that he needed to rededicate himself to football.

"Not everybody likes their job," Jacobs said his wife told him. "The guy that works at Verizon doesn't want to go in every day, but he sucks it up and sells his cell phones. So you've got to do what you've got to do."

The conversations with his wife and teammates also led him to declare Tuesday that he wants to play another three years in the NFL. Jacobs' current contract expires after next season.

"I went home and I realized that I do want to play this game a little longer, I don't want to leave. I talked to my wife and we've got to get it done. This is what I want to do," said Jacobs, echoing sentiment expressed earlier this season by Osi Umenyiora after his contract dispute.

"I talked to Ahmad [Bradshaw] and a lot of other guys and at the end of the day I'm playing for them. I don't really care about nothing else. I'm playing for them, I wanna win for them because [those are] my guys and they're always going to be my guys, years down the line. So I've got to do what I've got to do to stand up and stand tall for them."

The 6-foot-4, 265-pound back came up awfully small on Sunday against Miami.

Jacobs fumbled a handoff and dropped a pass in the opening series. He finished with 10 yards on four carries and one catch, in which he was stopped at the line.

Asked after Sunday's game about his role, Jacobs said: "I've got nothing positive to say. The most positive thing: I got family at home and I got a fast-ass car being delivered on Tuesday. That's it."

After exercising with students at Essence School in East New York as part of the NFL's Play 60 program, Jacobs was willing to discuss his situation with the Giants in greater detail.

"Things didn't go well for me because I'm not feeling well. I'm not happy," Jacobs said. "So I'm going to commit to it and I'm going to come through it 100 percent and be the best that I can if not for anybody else but my teammates."

In a contrast from his mood after Sunday's game, Jacobs was all smiles while interacting with the students at Essence School, to which the NFL donated a $10,000 grant for health and wellness programming or equipment.

Jacobs talked to students about the importance of staying physically fit and keeping out of trouble.

"Trouble is a hard thing to get out of and very easy to get in to" was part of his message, he said.

Jacobs then told reporters he got into a significant amount of trouble while growing up in Louisiana.

He said he spent "a couple of months" in a local detention center and paid a large fine for vandalizing cars outside of a church as a teenager. He said local police fingered him after matching his sneakers with sole marks left on the cars. He also said he nearly got in trouble with drugs. Those experiences, according to Jacobs, give delivering a message to children like he did on Tuesday a personal feel.

"I get along with these kids a lot," Jacobs said. "A lot of them they want to do well and you've just got to go out and give them that extra push."
