As a Jackets fan uninterested in moving Jenner, I can tell you nonetheless that he is not in the same category as Philip Danault. Jenner is solid defensively, Danault is elite. They could both score 50 pts, but only one of them is shutting down elite opponents while doing it. Anyways, the Kings aren't going to become sellers this year even if they continue to stink it up, neither player is moving.
Laine I could see going to a good team trying to get over the hump with playoff scoring, like the Canes. It would certainly involve retained salary and or cap dumps. He probably has to come back and play some solid games first too, hard to trade for a player when you don't know which version will show up. He hasn't played well since his concussion at the start of the year.
I do see Laine getting traded, and it won't be a pretty trade for the Jackets, but they're at the point as a franchise where they have more than enough value and their primary concern is getting the right players in the right spots. Laine is an inconsistent (albeit higher end) version of a lot of young scorers they have coming up, while Jenner's role can't be replaced by someone younger.
