After a difficult stint playing professional hockey in Finland’s top league from 2019-21 and a cup of coffee in AHL Belleville last season, our most improved prospect thrived in an expanded role under head coach Troy Mann and played admirably in his first NHL games. Thomson didn’t earn the distinction of most improved prospect by virtue of rising up from the depths of obscurity but rather by developing into a bona fide NHL-calibre player after looking like a wild card just a year ago. While fans of the Ottawa Senators have always wanted to believe in Thomson’s potential based on his pedigree, only this past season did it really start to feel like the Finnish defender had a guaranteed place in the future of this young NHL team.
