"He's a skilled young man," Kyle said. "He's going to play both ways for us and we don't usually do that. He's got legitimate sprinters speed."
Johnson helped lead St. Ignatius to the state championship last season as a junior, rushing for 407 yards and seven touchdowns. He also made 14 solo tackles and broke up one pass on defense.
Though he had offers from several MAC programs, a recent visit to Louisville's campus solidified Johnson's decision for the Cardinals.
"I think Louisville thinks he can play offense or defense," Kyle said. "He's aggressive as a safety but he has the speed (4.4) to play corner. Louisville likes that flexibility. He likes to hit."
Louisville has had a slew of commitments from high school prospects this summer and Johnson is the tenth prospect in the Class of 2010 for the Cardinals.
"He went to Louisville's camp and they offered early," Kyle said. "They were sincere with their offer and that caught Kevin's eye. He enjoyed their camp and came back from Louisville ready to (commit). Louisville is a great challenge and they were right there in the beginning."
