Jamal Adams promises Jets he’s barely scratched the surface

The Christmas present arrived for Jets fans just after 7 p.m. on Dec. 25.

Instead of appearing under their tree, it popped up on their iPhones, laptops or tablets.

“Just wrote down everything I will achieve & more. I promise, 2018 is my year!” Jamal “Santa” Adams posted on Twitter on Christmas night.

Adams had just spent some time at home, putting pen to paper and writing down everything he wants to achieve in the new year. It is an annual tradition for the 22-year-old rookie safety.

“I just wanted to start fresh — new goals for this team, new goals for myself,” Adams told The Post on Wednesday about the list. “It ain’t just for football. It’s life. I had some time on my hands. I wanted to spend some alone time and reflect on this year.”

While the Giants are dealing with a crisis because of the immaturity of Eli Apple, a defensive back they selected in the first round of the 2016 draft, the Jets are enjoying the maturity of Adams, their defensive back selected in the first round this year.

Unlike Apple, Adams gets it. He has displayed a leadership way beyond his age in his first year with the Jets and provides hope for 2018 and beyond for this team and fan base.

“The majority of it wasn’t about football. It was about life,” Adams said of his goals. “I think when you take care of what you want to do in life the right way, those things carry over to the football field.”

Adams would not reveal what is on his list for 2018. He said he won’t even tell his parents. But if he follows up with a year that is better than 2017, that should thrill Jets fans.

While the Jets quarterback situation might give you angst and you may not be sold on Todd Bowles, it is clear after this year that Adams is a keeper.

Since the Jets selected him sixth overall in April’s draft, Adams has been everything they could have asked for. On the field, he is fourth on the team with 73 tackles, six for a loss, with two sacks, five passes defensed, one forced fumble and two fumble recoveries.

Off the field, he has brought an energy and attitude to the defense. He also has embraced being a Jet, intent on changing the way this team is perceived.

When Adams looks back on 2017, he is thankful he ended up with Gang Green.

“It was a dream come true,” Adams said. “I’m right where I need to be. I love this organization. I love the people around here. I love where it’s going. This team has a lot of potential. We’re only going to get better. I wouldn’t trade it for the world. All of the ups and downs are a learning experience.”

Watching Adams in the locker room is dizzying. He bounces all over the room like a pinball. His voice can be heard most days, razzing one teammate and then moving on to another. The energy he brings is contagious and has led to a different vibe with the Jets defense this season. The dancing on the field that fans saw earlier in the season is all Adams. The guy pulls off a trick that is hard for athletes — he is super confident without being so cocky that he turns off teammates.

Instead, they embrace him.

“We know where this team needs to be,” Adams said. “We play best at the times when we feed off each other’s energy and we bring that swagger and have fun and let loose. That’s the platform — the energy and swagger we’re going to bring. When we go out there and just have fun as a team, the sky’s the limit. We just go out there and continue to work hard and get better in the offseason and correct what we need to correct for next year.”

Ask Adams what he thinks of the Jets’ 2017 season that will finish up Sunday against the Patriots and you get an idea what is at the top of his goal list for 2018.

“It was OK,” Adams said. “We didn’t get to the playoffs, so that’s the worst part about it. The playoffs is what everyone wanted in this locker room. It didn’t happen. We fell short. You learn from it and bounce back next year.”

Adams has big things planned for 2018. Happy New Year, Jets fans.
