Johnson averaged 20 points and 10 rebounds as a freshman at Duluth East and recently participated in the Nike All-American camp in Indianapolis and improved his standing as one of the nation's top swingman with a solid outing.
"Bringing the ball up the floor against pressure and staying back on defense are skills that I'm working on," Johnson told the Budgeteer his hometown newspaper.
"Nike was an excellent experience. I played on a three-on-three team with two guys rated in the top 10 in the country. Mostly, it was a confidence builder for me personally."
Johnson confirmed that he has been offered a scholarship by the Spartans and is considering the offer very seriously.
"I'm still in high school and trying to keep an open mind," Johnson said. "Hopefully by the end of July I'll have a list, but I probably won't make a decision this summer. I've been talking a lot with Wisconsin lately, and I've been to Illinois where I've scrimmaged on the same team as Dee Brown. That was an experience. I've also spoken with Purdue and Michigan State."
In all, Johnson is currently considering eight schools, including six in the Big Ten with no particular favorites. He says his main goal this year is to get better as a player and a person.
"I'm working hard to improve as a player and to prepare myself for college, academically and athletically."
