Nice try. I don't think either of those trades are really that good for Carolina or Vancouver. Skinner would be a nice get but he is a UFA soon. If Vancouver is willing to eat that much salary I personally would not have a problem giving up a 1st round pick for Tanev. That would truly help the defense next year as well.

The rumour out there on Skinner is a first round pick and a prospect. These picks come pretty near to a first.
Leafs use Skinner as a one season rental, and let him walk when the kids salaries kick in.
Carolina needs a change in net, so why not take a chance on Sparks he was the AHL's best, and Toronto has 6 goalies under contract. If they bury Darling, see if he can regain some confidence. No one is going to pick that salary off waivers.

You're not that far off base with Skinner but your timing for the trade is wrong. Your trade makes sense if he doesn't get traded until the deadline. At which point, he'll be moved for much less than he is worth. Players seem to be following the NBA style of dictating where they will play when they are in a situation they don't like. I think Tavares changing teams will open the door on a lot of bigger names hitting the open market.
