With a relative dearth of top-flight goaltending options available in free agency this offseason, the NHL goaltending carousel has been spinning madly with trades.

June 19 saw Jacob Markstrom dealt to the New Jersey Devils and Darcy Kuemper land with the Los Angeles Kings.

The Boston Bruins finally found an answer regarding Linus Ullmark's future and they did it just before the start of Game 7 of the Stanley Cup Final.

Boston traded Ullmark to the Ottawa Senators in exchange for Joonas Korpisalo, Mark Kastelic and a 2024 first-round pick that was originally the Bruins' first-round that they parted with in a previous trade. The Senators agreed to retain 25% -- or $1 million per year of Korpisalo's $5 million contract, which has four more seasons remaining.
