I find it interesting that
Rasmus Sandin and
Timothy Liljegren's names are not included on that list, given that they are widely viewed as the team's future on the blueline. I could see a scenario in which the Leafs might entertain trading one of them in a package deal for the right piece coming back - perhaps in a deal for a starting goaltender.
John Gibson and Carter Hart come to mind as options. Hart is especially interesting considering how young he is and what his ceiling as a goaltender is. Further to that, Flyers GM Chuck Fletcher had already announced this season that Carter Hart was not one of his team's untouchable players.
