COLUMBUS, Ohio — A collection of notes, insights, ruminations and did-you-knows gathered throughout the week that was for the Columbus Blue Jackets:Item No. 1: Werenski ‘noise’The news on Sunday that Brady Tkachuk had been traded to the Florida Panthers — that despite all of his public comments, he actually did want out of Ottawa — no doubt sent a shiver down the spine of Blue Jackets fans.At this point, you’d have to be naive not to at least worry about Zach Werenski’s long-term future in Columbus, now that so many key members of USA Hockey’s national team have forced their trades to NHL cities and clubs for which they’d really like to play.Quinn Hughes made it clear he wouldn’t sign in Vancouver and was traded to Minnesota. Two years earlier, Matthew Tkachuk made the same known in Calgary and was traded to Florida. Now his brother, Brady, has forced his way out of Ottawa to join him.Dylan Larkin has asked the Detroit Red Wings for a trade. Connor Hellebuyck reportedly wants out of Winnipeg.There are likely other shoes to drop, and Blue Jackets fans have to fear that two of them will belong to Werenski, who is now arguably the best player in franchise history.To be fair, Werenski has not indicated anything publicly, other than his wish to make it work in Columbus. Throughout his time in Columbus, Werenski has always spoken openly and honestly, and we should assume no different now.But the way the NHL is rapidly changing into an NBA-like funnel of top players to top teams, it’s putting fans on edge in a majority of the league’s markets.Werenski has made repeated comments that his experiences with Team USA, including a gold medal in Italy this past winter, have reminded him of what it’s like to win, and that winning in the NHL is one blank line on his incredible resume.After making the playoffs in Werenski’s first four seasons in Columbus, the Blue Jackets have gone six straight seasons without the postseason, tied with Chicago for the third-longest active streak in the league.When taken at face value, Werenski’s words are perfectly reasonable and fairly benign. Who doesn’t want to win?But when held against the reality that so many of his Team USA teammates are setting sail for new clubs, they can also land like a mild threat.
