Johnson is a talented but undersized winger who is a quick skater and is adept at passing and stickhandling. He does not play an overly combative game but is willing to go into tight areas if necessary to create scoring chances. As with many young scorers his defensive game is still developing and his size is sometimes a disadvantage.
Johnson finished the 2015-16 season with the AHL's Toronto Marlies after winning a championship in Sweden with Frolunda. Like several of the prospects in the Leafs' system, he is an undersized but highly-skilled scorer who plays with a lot of tenacity.
