The 6-foot-10, 210-pound Johnson visited the Cardinals in June and received a scholarship offer, since then he's become a major U of L target by the staff.
Johnson has more than a dozen offers, is likely to rise into the top 75 of the rankings and has proven his worth with his Dorian's Pride AAU team.
"I have been in the gym 24-7," Johnson said. "If I am not in my high school gym, I am in the rec gym. I have been working hard.
"A lot of hard work seems like it's paid off for me."
Johnson, who is still just 16 years old, said all the schools on his list are "recruiting me hard," and mentioned U of L, Michigan State, UNLV, Iowa State, along with Oregon, Arizona State, Texas A&M and USC.
But when asked about U of L, Johnson smiled. He said the visit was "really great," in June and said he's felt like the staff has made him a priority.
"They say I am their number one recruit now," Johnson said. "I feel like they are recruiting me harder. It's a great privilege for me.
"It's a great school and I really like the staff."
Johnson said he was "unsure" when he would narrow the list or make any kind of decision, noting "I'll sit down with my mom and coaches."
