I don't see Neal signing north of the border for any team. Carlson should easily resign with the capitals after the Orpik move.
Depends if he’s offered a huge deal Washington won’t match. But he has solid roots in Washington so I think he stays. I think him and Tavares are just using this as leverage to hammer their home teams for as much as they can.
I think we might see more of this in the future where stars go to their UFA period and not sign extensions in their last year. See Panarin as an example and I think we will see the same with Karlsson no matter who he plays with next year.
All I know is McDavids and Draisatls deals will look pretty good in 3years.
