I don't really see the point of trading Lias for Subban at this point, unless you're just really looking to unload Lias? You likely lose Subban on waivers if he doesn't make the team (And, if Quick and Petersen are still on the roster, he won't).

Only real reason I could see for doing it would be to buyout Quick?

I understand you are trying to build for the future but at the same time, this season coming is supposed to be a step forward. They are basically done unloading players for picks as their prospect pool is very strong. It is possible they still add picks but very few compared to years past. That Carter trade won't happen, I understand that JR is as some would call him an "idiot" but still doubtful for a second round pick. As for Andersson, no reason to move him; recently acquired for a chance to prove himself in a change of scenery while at the same time, why acquire another goalie? Unless you have a plan for Quick, there was no reason for that. I'm doubtful that the kings would look to take on Eriksson's contract with that term even with those shiny sweetners. The contracts seem ok at first glance other than that Amadio contract, I understand it's only for one year but he doens't get PP time and he plays a bottom 6 role.
