But Champagnat Catholic coach Mike Tunsil said after a visit from head coach Bobby Petrino and assistant coach Lamar Thomas that Johnson is a strong commitment to the Cardinals.
"It was never an issue of him leaving," Tunsil said. "He just wanted to make sure about the new coach and it couldn't have worked out better."
Tunsil said he had a previous relationship with Petrino, who had a player from Champagnat Catholic committed to Western Kentucky. Tunsil also has a previous relationship with wide receivers coach Lamar Thomas and defensive backs coach Terrell Buckley.
"It worked out to where they have a great staff coming in there," Tunsil said. "(Johnson) picked Louisville because of the school and because he liked it.
"He likes everything about it."
Tunsil said Petrino and Thomas made a "great" visit and noted Johnson will make his official visit to U of L this weekend.
Johnson helped Champagnat Catholic to the Class 2-A state title in Florida as a senior. He has told Cardinal Authority in previous interviews that one reason he picked U of L is because he "knew a lot of guys on the team." His former teammate Chucky Williams was a redshirt freshman this season and linebacker Keith Brown is a close friend from his high school days.
Cardinal Authority will keep you posted on Johnson's recruitment.
