The Fighting Sioux defeated Wisconsin and Ferris State to win the regional; falling to Minnesota 2-1 in the Frozen Four semifinals on a goal in the game’s final second.
2014-15: Johnson was one of seven skaters to play in all 42 games for for the University of North Dakota in his sophomore season. Overshadowed by some of the high scoring forwards for the Fighting Sioux, he finished the year with 11 goals and 13 assists and was +9 with 54 penalty minutes on one of the top teams in the country. North Dakota finished first in the National Collegiate Hockey Conference regular season, falling 3-1 to St. Cloud State in the NCHC semifinals and 5-1 to Denver in the third-place game.

Johnson is a skilled but hard-nosed center who relishes play in small areas and will go into tough spaces to create chances or retrieve pucks. Playing on a team with high profile scorers like fellow Blackhawks' prospect Nick Schmaltz at North Dakota, Johnson flies under the radar at times but is willing to do the dirty jobs that have led to success for the Fighting SIoux. He is capable at both ends of the ice well and is strong on the face-off dot. With a quick shot and a willingness to drive the slot, Johnson has the potential to score goals. Johnson has steadily improved his consistency — both in terms of engaging physically and and creating scoring chances — at the college level.
Johnson returns to North Dakota for his junior year in 2015-16 and will be one of the upperclassmen upon whom first-year head coach Brad Berry will rely to keep the Fighting Sioux among the top teams in college hockey. In terms of his NHL potential, Johnson's lack of power forward stature and high-end scoring skills could hold him back but his positional play, awareness and work ethic suggest he could have success playing in all situations in a second or third line role.
