Once again, I can say this about pretty much every other star player on this team. Difference is that those guys were already making the massive salaries when they chose to disappear entirely.
True to a degree but here are some differences: Letang makes more bone-headed plays than the other guys, Letang disappears for longer stretches on the PP than the other guys, and we have far greater depth in our system at Letang's position (including some PPQB types) than we have at forward.
Not saying Letang definitively SHOULD be traded, only that, there's a better chance and logically, it should be that way IF one of the big guys (besides Fleury) is on the way out to make cap room, etc.
What I'm concerned about: that Letang's bone-headedness might be partially or fully curable with a smarter coach / different type of coach.
Ideally, Letang negotiates this summer and does not ask maximum dollars based on his own play, instead agreeing to still be the highest paid D on this team but only at around $6M. If he does and we have a new coaching staff coming in, there's no way I wouldn't run with that if I'm Shero. Give him that 6M for as many years as he'll agree to it... for sure.
However I'm not convinced that he won't pursue maximum dollars, and if it's what has to be done to secure Geno here for the next 8 years, you do it. Also, unlike Geno or Sid being moved, if we moved Letang we definitely could get a return that makes it fair / worthwhile for us. With Geno or Sid you basically have to gut the other team to make it fair, and no team will ever do that. There are many possibilities with Letang. He could be moved for goalies like Bernier or Niemi + a young D and draft pick, etc. It's easier to make a Letang trade work for both teams.
