Upon returning from the trip, Johnson told Scout.com he enjoyed his time on CU's campus.
"It went really good," Johnson said. "I really enjoyed the school. I liked the academics and the overall presence of the school. I think the person who surprised me the most was the academic advisor. She was really on top of her game and that showed me how serious the school is about education. They want to keep you focused and studying."
Johnson said the Colorado coaches especially stood out to him.
"The coaches are great people; they're really funny," he said. "I learned a lot about coach (Tad) Boyle and he's a really cool guy. He lets the players play. Whoever gets the rebound brings the ball up the court which would really help me. I really liked all the coaches."
While he could trip to a couple of those schools during the fall, he says that he'll likely wait until the spring before signing.
"I'll probably wait until City of Palms (in December) to see if I get any exposure and after that I'll probably decide where I'll go," Johnson said. "I want to wait it out a little to make sure I have all my offers."
Regardless of when he decides, at the end of the day, Johnson could see himself staying close to home.
"It's important for me to play in the Pac-12 just to show everyone who stopped recruiting me," Johnson said. "That's my motivation right now."
