We still own RFA rights to Bjorkvist, Hallander and Filip Lindberg (the goalie) to my knowledge. None are 27 years of yet, so all will remain Pens property until then.
The ONLY way we land a Marner is if somehow the Leafs deem Tristan Jarry as the answer to their goaltending issues. And even then, I doubt we are able to pull it off.
As for Laine, I like the player. His presence on the PP would definitely help. That said, his value is nowhere near a first-round pick I don't care what year we are talking about. He is a reclamation project at this point. Not unlike his countryman Puljujarvi.
I am not trading much more than Reilly Smith for him at this point.
