You’ve probably heard by now that Erik Karlsson was traded out West.

The 28-year-old defenseman was sent to the San Jose Sharks from the Senators on Tuesday after spending the last eight seasons in Ottawa.

With the trade, the Boston Bruins no longer will need to face Karlsson multiple times in a season, something head coach Bruce Cassidy said makes life easier for his group of forwards.

Before Boston’s preseason game in China against the Calgary Flames, Cassidy addressed the trade, saying Karlsson is the type of player that makes others up their game. To hear what he had to say, check out the “NESN Sports Today” video above, presented by People’s United Bank.
