Wild fans can give me their opinions if they want, but as an outsider, I don't feel like Zucker is a piece you insist on keeping if you need to retool and I honestly have no clue how Guerin can look at the Wild and think they need anything but a retool. I don't know that the Penguins have what Guerin would want for Zucker (they do have pieces that Guerin likes, but maybe not in a Zucker trade), but I feel like Guerin needs to just rip the band-aid off and try to retool.
The Wild aren't close to being a cup contender, so if Guerin's goal is to win a cup as a GM, I don't know why he'd sit on assets like Brodin and Zucker. To me, those are the exact kind of guys you try to move if you're retooling. They're complementary pieces on contenders, but for retooling teams, they have more value as trade chips than as players. Not only that, but I think Zucker and Brodin are also very replaceable for the Wild, considering Suter, Dumba and Spurgeon is a great top-3 D group and they have Kaprizov coming next year.
