2009-10: Johnson skated for Calumet High school in Michigan's Upper Peninsula and played for the Ojibwa Eagles midget AAA team in Hancock (home of Michigan Tech). He was the leading scorer for Calumet with 59 points as a sophomore and scored 8 goals with 11 assists in 21 games with the Eagles. Johnson was selected by the Fargo Force in the fourth round of the 2010 USHL Futures Draft.
2010-11: Johnson was named Michigan's Mr. Hockey after his junior season at Calumet and also skated for Little Caesars' U18 team, the USHL's Fargo Force, and the US National Team Development Program. In 30 games with Calumet, he scored 37 goals with 40 assists. He played 13 games with Little Caesars and scored 3 goals with 2 assists and had 16 penalty minutes. In six games with the NDTP, he scored 5 goals with 1 assist. In five games with Fargo he was scoreless and minus-three with 2 penalty minutes. The Windsor Spitfires signed Johnson to an OHL contract in May 2011.
2011-12: Johnson skated in all 68 games for the Spitfires in his first OHL season. He finished the season with 18 goals and 20 assists and was minus-five with 44 penalty minutes. After finishing fourth in the West Division the Spitfires were swept by Memorial Cup-bound London in a first-round playoff series. In four playoff games Johnson had 2 assists and was minus-one. He was invited to the NHL Draft Combine and ranked 52nd amongst North American skaters in Central Scouting's final rankings prior to the 2012 NHL Draft.
Johnson's best asset is his break-neck speed. He is a simply phenomenal skater and at times it looks effortless when he is blazing around the rink. He uses that speed to drive defenders wide and take the puck to the net and he'll also use it to forecheck and assert himself physically. Johnson is still quite raw in the offensive aspect of his game but the potential is there for him to become a consistent offensive force.
It's hard to say just how good of an offensive player Johnson will become, but he could get a top-six role in Windsor this fall, so the opportunity will be there for him to advance that part of his game significantly. Regardless of how well his offense develops, his speed, energy, and physicality should at worst lend to a career as a tenacious, two-way third-liner.
