Proof that there truly is some Anakin left in Darth Vader: he still doesn't like sand

This wasn't the sub's first trip to the Titanic, so the previous successful dives probably instilled a false sense of confidence in the design. The problem with carbon fiber in this application is that it degrades with use, and the degradation doesn't occur in a predictable way. It might work a handful of times, and then spontaneously fail with little to no warning. Additionally, while strong in tension, carbon fiber is weak in compression, and in a situation where the vessel has higher pressure on the outside than on the inside, that puts the hull in compression. In aerospace applications where the pressure is greater on the inside, carbon fiber makes more sense. Steel and titanium are much more predictable for deep sea applications due to their fatigue characteristics and compression strength.

Looking at the way Yzerman has been drafting and constructing the team, it appears to me that he favors big, physical defensemen, and even those who are effective offensively are responsible in their own end (e.g. Seider, Edvinsson). I don't feel like EK65 fits this mold (especially with his unfortunate injury history that's hopefully behind him). And since he's 33, I'm not sure how well he fits the team's competitive window. I especially don't see Yzerman parting with draft picks or prospects for Karlsson.
The team has a lot of depth, especially in the prospect pool, so the biggest need from my perspective is top line scoring talent. I personally feel like the Wings would be more likely to target someone like Alex DeBrincat or Auston Matthews if they were looking to spend $8M+ on a player this offseason.
Dr. Becky had a great segment in her video today about it!
