I have zero problem giving Yzerman credit for his work in Tampa. He is the GM who hired Cooper to an AHL job out of the USHL and is also the GM who promoted him to the NHL a few years later. His staff had tremendous success finding genuine contributors outside the 1st round (Kucherov, Point, Palat, Gudas, Cirelli, Joseph, and Colton) and Vasilevski was a great pick at #19. He flubbed the Drouin pick, but managed to sell him for Sergachev 4 years later. I think it is very fair to credit him with building one of the better cores this league has seen in the cap era.
However, I have been fairly unimpressed by his work in Detroit. He had to dig the Wings out of a massive hole and I think the idea of a long, patient process was absolutely the correct one for that team. And I really like the prospect pool that he's built. A bunch their prospects are high end and developing right on schedule. I was willing to give him the benefit of the doubt on 'patience' until this deadline.
In a buyer's market with Larkin getting injured, I think he did a huge disservice to that franchise by standing pat. He could have upgraded the middle of the lineup without giving up any pick/prospect that was among his 10 most valuable futures assets. He could have made a notable acquisition with a 2nd rounder and a prospect who is outside their internal top 6-7 guys. I understand not going all-in this year by trading a top prospect or a 1st rounder, but that wasn't the cost required to make meaningful upgrades at this deadline. Giving that team some help to make the playoffs for the first time in years should have been a priority worth giving up a couple mid-value futures assets that are frankly unlikely to turn into difference-makers given the crowded prospect pool ahead of them.
They have a top 5 prospect pool and they own a draft pick in every single round of every future draft. Failing to leverage that for any help in a buyer's market given heir place in the standings approaching the deadline was a huge failure in my eyes. It erases a ton of my willingness to give him the benefit of the doubt on preaching patience. Not every team should be satisfied 'just making the playoffs' but the Red Wings should absolutely view 'just making the playoffs' as a tangible goal right now.
