"It was very good," Johnson said. "I got a lot of good work in and learned some things. I really feel like I got to connect with the coaches a lot more. It was just really comfortable and really smooth-running.
"He's just a great coach," Johnson added of Horton. "When he's coaching you it feels like he's a friend, like he really cares about you. He really cares about getting the details right. He's just a phenomenal person."
Johnson is now up to 5-11, 193 and has a 40-yard dash time in the 4.4 range.
Making a return trip to Auburn to visit with the coaching staff and get to know them better, Johnson said the Tigers are definitely staying strong in his mind.
"They stack up just fine," Johnson said. "I think they are really going to surprise some people this year. They've got a bright mind in Coach (Gus) Malzahn and I think he's going to transform things. I think they'll be just fine.
"I think the offense fits me well," he added. "They get guys the ball in space and give playmakers a chance to make plays. I feel like that's something that I could really embrace."
The MVP of last season's Super Six as Madison Academy rolled to a state championship in Jordan-Hare Stadium, Johnson is just now getting back into form after his surgery kept him from the playing field for several months. Smiling and having fun, he said it's just great to be back doing what he loves.
"It just puts a smile on my face because I know that I missed it so much," Johnson said. "I didn't get to play football and it just really wore down on me. Getting the chance to get back out there and compete is awesome."
Up to nine offers at the moment, Johnson said that Auburn, Alabama and Florida State are his top three right now with all three equal. Hoping to add more offers as he gets back on the field this fall, the speedster said the goal is to win another title.
"The process has been kind of slow lately, but I'm perfectly fine with that," Johnson said. "I have a lot of schools that I like and a couple more that I would like to get. Things are just fine with me.
"I really feel like we can do it again," he added of the 2013 season. "It's going to be tough with the schedule we face. We've got a lot of tough opponents. Everybody is going to be gunning for us. I feel like as long as we stay focused and do what we're supposed to do then we'll be back in the same spot we were last year."
