2014-15: Johansson appeared in two SHL games with Brynas — splitting the year between Allsvenskan and the Brynas U20 team.

In seven preliminary games for the Brynas U20 team Johansson was 4-3 with a 3.47 goals against and .895 save percentage.

Johansson is a goalie with a big frame who likes to play deep in his net, a style popularized by fellow countryman Henrik Lundqvist. He is still fairly early in the development process and given his limited experience and exposure to elite competition, he is still a work in progress both in his technical skills and mental game.
Johansson is playing for Almtuna in Sweden's Allsvenskan on loan from SHL club Brynas in 2015-16. Playing in 48 of 52 games for the seventh-place club in the regular season, he had respectable numbers in the regular season and is seeing the bulk of action in the Kval Series playoffs. Johansson's size and durability suggest he can be a workhorse in net. He has yet to sign an entry-level contract with Buffalo but has the ability to one day be an NHL-caliber goaltender.
