Karl's words after the quote from Sheng's tweet:
"Then again, that's not my concern, it's not something I can do anything about, it's not my position in the organization, my position is to play hockey. You have to put the trust in the people around you that deal with those type of things and here it starts with Doug Wilson."
Anyways, I'm sure Karlsson is not the only one that thinks the team can still make the playoffs this season and can be competitive next year and beyond. There's almost no chance Kane, Couture, Hertl, and Burns think any different. It's not their job of course, as Erik alluded to, and they'd never say it publicly, but they've all been around long enough to know that if they can get better goaltending and have some young guys join the team and contribute then they'll be able to win more games next season. And it goes without saying that if Karlsson plays like he is now then he's the biggest part of the solution outside goaltending.
