All the best to the talented people at Vancouver’s Sportsnet 650 and Calgary’s Sportsnet 960, both of which were shuttered this week by Rogers. This industry stinks sometimes.On to a dramatic week in the NHL, where the suspense is building on what could be a franchise-defining decision for two teams.Well, things have certainly slowed down since the last time we were in your inbox. One week ago, we were digging out of the chaos of a week of blockbuster trades and star-adjacent UFA signings, blissfully unaware that the monster Leo Carlsson offer sheet was about to change the financial landscape. This week? There’s not quite as much news to chew on. But there’s some, including a resolution to that other offer sheet…The Mammoth match on HaytonAdmittedly, in the aftermath of the Carlsson deal, the New Jersey Devils’ offer sheet to the Utah Mammoth’s Barrett Hayton feels almost quaint. A one-year deal worth just under $5 million? Compensation that didn’t include any first-round picks, let alone four of them? Adorable!But while the Devils’ attempt didn’t force us to rethink modern salary structures, it was tricky in its own way. Remember, teams that match an offer sheet can’t trade the player for a full year. In Hayton’s case, that means that if the Mammoth matched, they’d walk him right up to unrestricted free agency a year from now and risk losing him for nothing. Would they really roll the dice on that outcome, or would they take a second-round pick from New Jersey and call it a day?Now we know: The Mammoth have matched the offer, meaning Hayton stays in Utah and the Devils come out empty-handed.This always felt like the most likely outcome, even as there was enough uncertainty to make it worth the Devils’ while to find out. The Mammoth will now get one more season from the fifth overall pick in the 2018 draft, with the possibility of an extension still on the table down the road. They’ll no doubt be hoping he improves on last year’s 10-goal, 25-point output; his career high is 46 points in 2024-25.As for the Devils, they miss out on the player but now have nearly $5 million in cap space that they can work with. Is there anyone left on the market for them to use it on? Not really, but new GM Sunny Mehta is clearly willing to think outside the box.And with the offer sheet undercard now taken care of, we can move on to the main event.Decision day for the DucksThe clock is ticking. And by tomorrow, Pat Verbeek has to make his call.The Anaheim Ducks GM is facing one of the tougher decisions in years: Does he blow up his team’s salary structure by making Leo Carlsson the highest-paid player (by AAV) in the league? Or does he take four first-round picks from the Philadelphia Flyers and let Carlsson walk, essentially hitting reset on what had looked like a successful rebuild effort?
