However, one of the reasons the local talent committed to the Volunteers was assistant coach Frank Wilson, a fellow native of New Orleans who coached at O.P. Walker High, where the 6-foot-2, 296-pound prospect is currently enrolled.
On Sunday, the four-star prospect said the coaching change hit close to home.
"I think it is a great opportunity for him and his family," Johnson said of Wilson's switch to LSU. "He is going to be a great attribute to LSU. I lived close to his house growing up and he was the head coach at my high school before I got here. He's a great person and a great leader.
"I've been expecting a call from him," Johnson continued. "Coach [Les] Miles and coach [Jon] Chavis said they'd do anything to get me there, and I guess anything is possible with recruiting.
“A commitment is a commitment, but I haven't signed on the dotted line yet."
Could Wilson's move to LSU be enough to alter Wilson’s decision to part from his current commitment?
"I didn't just connect with coach Wilson," Johnson responded. "I also have a good relationship with defensive line coach Ed Orgeron. Tennessee is a great place, but LSU is still high on my list."
While it is expected that Wilson would take part in Johnson’s recruitment, defensive coaches Brick Haley and John Chavis are already courting the four-star prospect.
“I have a good relationship with the staff so far, so Wilson’s move will only help,” Johnson said. “There is definitely a long time until I need to make my decision final. It does give me something to think about though.”
Johnson finished his junior season with 89 tackles and 16 sacks.
