The 6-foot-10, 190-pound Franklin Central (Ind.) forward, who occupies the 42nd spot in Scout.com's Class of 2007 rankings, wasn't quite ready, according to his high school coach, Mark James.
``He hasn't really even played varsity basketball yet," James said. "We've hit him. He played about eight games – sparingly. He's really a puppy right now."
``He's got a ton of potential," added James. "No one really knows the limit to his potential. He's just so green to the game."
Johnson, 16, will be the first to tell you he was somewhat surprised by his success this summer.
``I'd never played against that type of competition," Johnson said. "This summer really helped my confidence a lot."
It's safe to say that James can pencil in Johnson for far loftier numbers.
``To be honest, I was kind of frustrated last season, but it really motivated me," Johnson said. ``I had to do something – and that's what I think I did this past summer."
Johnson is a big-time athlete who runs the floor, alters shots and can defend a variety of positions due to his length. He still needs to get stronger, work on his shot, improve his passing ability and just get more game repetitions.
``He's the type of kid who may be able to step out," James said. "We'd like for him to be able to play the three as a senior."
``The biggest thing that college coaches like about him is his length," added James. "He's got a knack for being able to block shots and keep them in play – like Bill Russell used to do."
Johnson admits that he hadn't received a single letter prior to April, but all that changed – quickly.
``I took an unofficial to Butler and I really liked it," he said. "The biggest thing for me when I'm making my decision will be the coaches."
