When the Ottawa Senators traded a 2024 first-round pick, Mark Kastelic and Joonas Korpisalo for Linus Ullmark, it was met with unbridled enthusiasm.
Trading the goaltender who finished dead last in the entire NHL in goals saved above expected (GSAx) per Evolving-Hockey -- a stat that captures the difference in the number of goals a goaltender allows against how many they were expected to let in based on shot quality -- will do that. Shedding the remaining four years and $12 million on Korpisalo's deal was a stunning and not prohibitively expensive development on its own.
