Sopanen is the younger brother of one-time Devils' prospect Vili Sopanen and Iiro Sopanen, both forwards. Among the top defenseman prospects in his age group, injuries kept him off the ice for much of the 2013-14 season and he was not selected in the 2014 NHL Draft. His size and raw skills have garnered attention. When healthy he is an effective two-way defender with the skating ability both to defend in his own zone and create plays off the transition game.
Sopanen after being hampered by injuries the two previous seasons, appeared to get his career back on track in 2014-15. Ability-wise, he compares favorably with other young defensemen but the lost time has stunted his development somewhat in terms of positional and tactical play. He still has the potential to be an effective two-way defensemen one day and should be an intriguing late-round option in the 2015 NHL Draft.
