"It was definitely a shock because I hadn't heard anything from Louisville before they sent the offer," Johnson said. "I talked to the coach last night..Coach (Larry) Slade. He was telling me about where he's been, his experience and the people he's coached. It was definitely a good conversation."
Johnson, who also plays basketball, has been clocked at 4.5 seconds in the 40-yard dash. He said Slade told him Louisville felt he could help them at safety.
"He really liked my athleticism and ability to play the run and pass at free safety," Johnson said. "I don't know much about Louisville. I'm definitely interested and hopefully I'll get a chance to visit and check out the campus."
"There are a couple of schools I have high interest in but I don't have any favorites," said Johnson. "I'm interested in UConn, Michigan State, Maryland, Virginia and NC State."
Johnson plans to attend the Nike Camp at Penn State on May 2. He's not in a rush to make a decision and plans to take a several official visits in the fall before picking a school.
"I'm looking to take official visits sometime during the season," Johnson said. "Definitely the coaching staff and environment are two big factors. Those are two of the main factors. I like a coaching staff that I can get to know the next four years."
Johnson is considered one of the top prospects in New Jersey. "He's a 6-3 free safety with good speed," Pennington coach Jerry Eure said. "He's covers a lot of ground and will come up and stick you."
