Johnson, who was the 100 meter state champ in 2009, will enter school June 28, and his goal is to make an immediate impact.
He also expects to be able to spend more time focusing on bettering his game after a high school career in which he spent plenty of time helping teammates understand schemes and technique instead of focusing on himself.
"I expect to ball out. I expect to play my first year,'' Johnson said. "I expect to come out there and make an impact because in high school, as more of a leader, I had to help other people protect their positions, let them know what they were doing and make sure I knew what everybody else on the field was doing.
"I had little time to work on myself. College is all about your position and yourself.''
That position, Johnson said, will be slot receiver. At 6-foot-1, his size could create matchup difficulties for cornerbacks.
But before that can happen, he needs to get his body right, and add weight. The spring track season took its toll, with a right hamstring injury early on and the loss of weight from extensive training.
After finishing sixth in the 100 meters at Thursday's NJSIAA Meet of Champions, Johnson weighed 175 pounds.
"I'll put some weight on when I go up there because they definitely do want me to do that,'' he said. "By the season, I believe I will be 190. Definitely, I'm a slot receiver. I feel like I can go in the backfield, do that ‘Wildcat' and I can do some damage.''
Johnson will contend with a handful of receivers for playing time, including returners Mohamed Sanu, Mark Harrison, Quron Pratt and Tim Wright, as well as freshmen Jordan Thomas, Jawaun Wynn, JT Tartacoff and Jeremy Deering.
But Johnson will have to acquaint himself with the receiver spot since he spent much of last season lined up in the Egg Harbor Township backfield. He rushed for 973 yards and 10 touchdowns as a senior.
"With my speed on the field, I love it. I can't wait,'' Johnson said. "I'm very excited. I get to focus on myself and make myself better because we've got enough coaches now that can work with every position, with everybody at the same time. So, I'm happy. I'm so into it.''
Johnson won the 2009 Meet of Champions 100 meters in 10.67 seconds. His time this year was 10.74 seconds.
"I didn't slow down or anything, but I did feel it pull a little bit,'' Johnson said. "If one of those pops, it may end up going into the college career.''
However, the Meet of Champions may not signal the end of Johnson's track career. He is contemplating running for the Scarlet Knights.
"If my coaches think it's ok,'' Johnson said, "I'll go in, run track and make myself faster and better myself on the field.''
