The NHL offseason has been extremely chaotic, and it’s far from over. But after the biggest frenzy of the year, through draft week and the early goings of free agency, most rosters are taking shape. And some of those teams and unresolved situations are raising red flags and sounding the concern-o-meter. Let’s look at some concerning trends developing around the NHL.NHL offer sheets are just businessSean Gentille and Sean McIndoeThe Blue Jackets’ directionConcern-o-meter: 6/10The concern ticked all the way up to a 10 in Columbus as the Zach Werenski situation spiraled. The temperature has obviously lowered now that he’s off the trade market — but not enough to stay off the radar entirely. Werenski expressed that he wants to win in Columbus, but a contract extension in 2028 isn’t (and can’t be) written in stone just yet. The team likely has to show real progress until then, so the pressure is on to keep building around Werenski. The problem is that the Blue Jackets front office was a little busy with the Werenski saga at the busiest point of the offseason. There was a frenzy of player movement that Columbus was largely uninvolved in, and understandably so. It was likely pretty tough to widen the scope when everything was swirling around the potential of a franchise-altering trade. Through all the chaos and noise, management did make a couple of deals, like acquiring Valeri Nichushkin from Colorado and signing Ryan Lomberg to help replace some free agent exits. And those types of depth moves were likely always going to be an offseason priority, since a lot of Columbus’ strategy revolves around internal growth from players like Adam Fantilli, Kirill Marchenko, Kent Johnson and Denton Mateychuk. But after stumbling down the stretch and out of the playoff picture entirely, the Blue Jackets may want a little more certainty around their up-and-coming core. That’s the best way to make the most of the next couple of seasons with Werenski and show him that this team is on the right path. So it’s up to management to get creative, with fewer trade targets and free agents available at this point in the summer. The Stars aren’t any betterConcern-o-meter: 6.5/10The Stars still look like contenders. But this team is coming off its worst playoff losses yet, after exiting in Round 1 to the Wild. Sure, the playoff format exacerbated that; it’s unfair that the second-best team in the West had to face off against the No. 3 team. But at the end of the day, they don’t ask how Dallas was eliminated; it’s how many rounds this team went and how many trophies it ended the season with. After reaching the Western Conference final in three straight years, the Stars were ousted in Round 1. And the team hasn’t done enough to improve its chances of moving further next season. Management tried with a Werenski trade offer that would have added one of the best defensemen in the world to its blue line. That would have opened up a little cap space for a Jason Robertson extension. When the move was vetoed by Werenski, it left some collateral damage in Dallas, like Thomas Harley, who was included in the return. If that wasn’t a tough enough blow, there is still no extension in place for Robertson. There is officially a deadline on that now, with his arbitration hearing scheduled for July 25. But that outcome could actually make matters worse for Dallas; say he’s awarded a one-year extension, that walks him straight to unrestricted free agency next July. If the Stars can’t find middle ground with him financially now, can they in a year, when the cap (and market prices) rise? Will the team be willing to commit more to him when he’s a year older?The best outcome for Dallas is a multiyear extension for Robertson, even if it’s a few million above Mikko Rantanen’s $12 million cap hit. But the way things are heading, the Stars could find themselves in a bind in the next few weeks: At risk of losing their best winger for nothing next year, with a team that is a year older and under even more pressure to go the distance.
