I don't think any team should move forward thinking the cap will increase next year. Even if there is a vaccine, unless businesses find their ways out of this we might be in a terrible economical crisis so people will spend less. Sports leagues are going to get hit.
As for Subban, I'd been interested before but I have very big doubts on PK's physical condition. He's usually very active on social media with his workouts and he hasn't posted anything about training in LA..
I rather we make moves that really moves the needle. Not sure about Subban at this point.
