But Sunday made things a lot more interesting. Johnson, who is 6-foot-3 and 285 pounds, finally received the offer from Oklahoma he had been hoping he'd get for a while.
Johnson visited OU for a spring practice and started to develop a relationship with defensive line coach Jerry Montgomery. One thing that stood out during that visit was how much help OU needs at the position.
Johnson was hoping for an offer during the spring evaluation period. It didn't come, though. He was all set to participate in an OU satellite camp in Carrollton, Texas, in June but a pulled hamstring kept him from competing and the two sides looked like they might be going their separate ways.
"Part of me did think the offer wasn't going to come," Johnson said. "I had heavy interest in them and then things kind of just stopped. I kept wishing for the best."
The best happened last weekend. OU offensive coordinator and Johnson's main recruiter Josh Heupel emailed Johnson on Saturday, telling Johnson to call Montgomery.
Johnson made the call Sunday, and Montgomery officially extended the offer.
"He talked about how much help OU needs at defensive tackle and how I know that's true because I saw it with my own eyes," Johnson said.
In the spring, Johnson talked about LSU and OU as his two favorites. The OU offer now has the Sooners back in play, but he isn't about to rush anything.
Johnson has visited OU and Baylor but said he has not seen KSU or OSU yet. He will not make a decision until he sees all four schools.
"I plan on committing during the season so I'm not about to make a decision just to make one before my season starts."
Johnson said he would have liked to have made more unofficial visits this summer but was unable to because of his parents' work schedule. Instead he's only been focusing on what he can control.
"I'm not getting slim, but I'm getting trim and feel a lot leaner than before," Johnson said. "I'm really excited to show everybody what I can do now."
