Soderstrom has good size and is technically sound in the crease. He is considered a project and will need time to develop but his skill set suggests he has the potential to be an elite goalie one day.
Soderstrom is back in Sweden after spending part of the summer in New York — both at the Islanders' prospect camp and with the Sweden U20 team at the evaluation camp in Lake Placid. He has played well when called up on to back up veteran Axel Brage with HC Vita Hasten in AllSvenskan in 2015-16 and was in net for Sweden's U20 team during the World Junior Championship. Soderstrom is on track in terms of his long-term development and his progress to this point suggests he could be an NHL starter one day.
