"My Mom, she didn't want me to go to far away like up north, she wanted me to be close to home," Johnson said. "Western Kentucky is close enough for us.
"She's happy about it, she's actually about to cry."
After making his decision, he called his recruiting coach--WKU assistant JaMarcus Shephard--to tell him the good news.
"I called Coach (Shephard), he was like 'Jason, have you thought about committing?'" Johnson said. "And I said 'yeah Coach, I'm ready to commit.'
"And he was like 'well good, you're on-board!' Him, the whole coaching staff, they were excited about me committing."
Johnson projects at either safety or receiver for WKU, saying he'll play "whatever spot they (WKU) want me to play."
"I'm best at chasing the ball, I'm a ball-hawk," he said. "Reading the quarterback, that's probably my weakness right now, but I'm working on it in practice, working on reading the guards too."
He plans to take his official visit to WKU "sometime" in December.
Some of the newest Topper commits (like Quin Jernighan, a consensus three-star prospect,) haven't received official ratings yet.
