Trade explanations:
Colorado: The Avs clearly have one too many LD and will likely need a new middle 6 PK-capable winger. They also get a legit RD prospect.
Toronto: Gets their goalie (cost controlled for 3 years) and a puck-moving RD at good value, both of which are needs. Plus, they get Vilardi and draft stock.
Philly: Gets a legit top-scoring winger and can move on from an obviously unhappy Provorov, plus their contracts perfectly swap so there's no worries there. If an extra 2nd needs to be given to the Flyers by LA, so be it.
