Now, it is.
The DePaul Catholic High (Wayne, N.J.) cornerback made the call today, ringing Rutgers coach Greg Schiano to give a non-binding oral commitment.
"I was with my coach and told him I had to tell him something," the 6-fot-2, 185-pound Jacobs said. "I called him and told coach Schiano I thought it over, talked with my parents and I want to come to Rutgers. He said that was great news, and to call him again tonight.
"I feel a big weight off of my shoulders."
He made 61 tackles and had four interceptions as a junior. He also returned two kicks for touchdowns and averaged 8.1 yards per carry on 38 attempts and scored three touchdowns at running back.
"I feel good because I think Jersey football is some of the best," Jacobs said. "A lot of kids are going to Rutgers, so I think we'll be really good."
Jacobs has been on the Rutgers campus at least a dozen times in the last 12 months, including three times in the last month.
He was there during a get-together after the Big Man Academy earlier this month, and was at the Schiano Shootout 7-on-7 Saturday. And after that event, he was getting a feeling Rutgers was the place for him.
"I think that kind of sealed the deal," Jacobs said. "I was pretty sure, but wasn't (100 percent) sure, so I decided to talk with my parents, and we decided that would be the time to do it. They wanted me to be happy wherever I go."
Jacobs acknowledged he nearly committed to Rutgers at the 7-on-7.
"I thought about it," he said. "I talked about it with my parents and I think it was a good fit for me. I think we can win a national championship. I wanted to join them, and I think it will be really good."
Jacobs said the Scarlet Knights moved to the forefront of his recruitment during visits to campus in the spring.
"When I was at practice, I liked the way coach (Jeff) Hafley and coach (Greg) Schiano coached the defensive backs," he said. "They practice real intense and that's how I like to practice."
