He made his first visit to IU about a year ago at this time. His mother accompanied him on the trip and they enjoyed the campus, what the school had to offer academically and built quick relationships with the IU coaching staff.
Since then, the 6-3, 280 pound offensive guard from Olentangy Liberty High School in Powell, Ohio has visited IU three or four more times.
Wednesday, he made it official when he gave Indiana coach Kevin Wilson his verbal commitment to play football at IU beginning in the 2015 season. He committed to IU the same day that Joe Belden made his announcement which now gives IU six commits in the class.
"In late April I took some final visits but when I came home I knew that in my heart I wanted to play football at Indiana and since then I've been waiting for the right time to make that announcement,'' Littlejohn said. "Basically, since the first time I visited IU I knew down deep that it was the place I wanted to play. They have an unbelievable campus environment and I've grown really close to the staff there.
"I just think Indiana is the perfect fit for me.''
Littlejohn had lots of good things to say about Wilson and his staff and the way they have stayed connected with him since that first visit a year ago. And he can never talk about IU to friends without mentioning one key component: the facilities.
"I would put Indiana's facilities up against anyone in the country,'' Littlejohn said. "It's amazing the resources we have on hand to be able to get bigger and stronger as well as perform at the highest level in the classroom.''
Littlejohn has been described as a blue-collar interior lineman with plenty of upside. He has added 10 pounds to his frame since the end of last season and is poised for a solid senior year of high school football.
"I think Indiana recruited me for my athletic ability above everything else,'' Littlejohn said . "I'm not the tallest guy but I move well for my size and I'm strong, too.''
He said he is undecided in what he plans to study. A few possible options are Education, Sports Physiology and Business.
"I'm not exactly sure right now on my major but I have a lot of good options at IU,'' Littlejohn said. "Of course, I've heard a lot about the Kelley School and we checked that out when we there on a visit. Right now I'm just focusing on finishing my senior year of high school strong.''
