Now Johnson plans to head back later this month.
The three-star was joined by his brother, elite 2016 receiver Collin Johnson, and the pair got to check out USC.
"USC was good," said Johnson. "My brother and I enjoyed. I loved the stadium and being inside the Coliseum. I really liked it there. I grew up looking at SC so that was a great experience. Checking out the Heisman's was really cool."
Johnson spent a lot of time talking with the coaches there.
"Coach (Clay) Helton is the one recruiting me and Coach (Johnny) Nansen is the running backs coach so I talked with him for a little bit. We sat in their meetings too. We also got to talk with Coach Sark (Steve Sarkisian). It was good. Their practice was filled with energy and they have a bunch of guys competing. I like how they were there."
Johnson and his brother had hoped to visit UCLA that same weekend, but with the school on spring break, decided to push it back for when the coaches and players are there and also for a chance to see the Bruins practice in spring.
"We're going to go back and visit UCLA this month," said Johnson. "I'd like to be able to be there and see it all the way and see the coaches and the team practice."
Johnson said they've been talking regularly with UCLA coaches, with both running backs coach Kennedy Polamalu and NorCal recruiter Angus McClure being in communication.
"UCLA could offer this spring, so we just want to get down there and check out the school," said Johnson.
This weekend, Johnson will be in Arizona and is hoping to hit both Pac-12 schools in the state.
"I'm going to Arizona on Saturday for their Junior Day and we're hoping to visit Arizona State while we're down there," said Johnson.
"USC could be the next closest," said Johnson. "They're the ones I've probably talked to the most that hasn't offered yet."
Johnson is passing on the 7v7 circuit, while his brother, a receiver stuck in a ground-oriented offense, which of course, benefits Kirk, maximizes the passing game of 7v7, plays in it.
"I'm not doing 7v7, just doing offseason work and training for football right now so I'll just do the Oakland Nike Camp next month," said Johnson.
