It’s not often Dallas Stars general manager Jim Nill has made a trade for a player under the age of 23 since he took the helm in 2013. Since acquiring Tyler Seguin on July 4th that year, Nill has traded for only two players under that age threshold - Mattias Janmark, whom he acquired from the Detroit Red Wings in 2015; and Dillon Heatherington, whom he acquired in 2017.
Janmark went on to play four full seasons with the Stars, and suffer a near-career ending genetic knee injury which he fought to return to action from.
