Johnson has looked good for his age, but hasn't produced much.
In his limited amount of games, he has shown great agility and puck handling ability. He also has slightly improved his work on the boards.
Stat-wise, he recorded 1 assist in 4 games in the regular season,
and in 6 games in the playoffs has 0 points, and a -1 rating.
As for your question,
I can't see a 2nd liner out of him so far, but definitely a good 3rd line player.
