"After the camp, I actually got to sit in the office with all of the coaches," Johnson said. "It was humbling. With (coach James Franklin) being one of the top five coaches in college football, for him to even have the time to speak with me is a great blessing. Then, for him to extend me an offer, I can't even put it into words."
Johnson is strong in coverage and he is physical against the run, but it was his speed in the 40-yard dash, at this size, that led to the offer.
"I ran a 4.52," he said. "I talked to them before it and they said they want to see me run at least a 4.6, and I did it at 190. I have to get down to 4.4."
Johnson enjoyed working with the coaching staff during drills, and he found the familiarity with their style.
"The camp was similar to what we do at St. John's," he said. "It was up-tempo, fast, and a lot of competition. It was the same principles are DB coach has for us when we go. We also put in a lot of work in at St. John's, before practice, after practice, weekends, week days, early mornings, late nights."
After the camp, Johnson headed to Ohio State for a Saturday visit and camp so he did not get a chance to walk around the campus or spend more time speaking about the academic side of the school.
However, this was not Johnson's first visit to Penn State. He made two others, including one for a 7-on-7 last summer.
"I walked around a little bit of the campus before," he said. "It's a beautiful place. It's got to be one of the top five college campuses in the country."
During his most recent trip, he also had a chance to catch up with former St. John's standout Ayron Monroe.
"I talked to him a lot," Johnson said. "I met him when I was first coming to St. John's and he was leaving as a senior. He's in competition for a starting position. I think this year is going to be a breakout season for him."
