Oh, this is a GREAT idea for Anaheim, because the only long-term asset in the deal is Liljegren, so of course I love it for the Ducks, but what does Toronto get out of it?!? The Maple Leafs lose their best defensive defenseman and their best defensive prospect -- and a rightie, at that -- and what do they get in return: a good but not great middle-six left-handed forward plus some cap space.
Substitute Connor Timmins for Timothy Liljegren and it would STILL be a bad idea for Toronto (as it would be, then, for Anaheim). I'm with
@TheresAlwaysNextYear -- Treliving wouldn't entertain this offer for a nanosecond.
P.S. My original comment was based purely on the obviously doubtful Team Title; it wasn't until after I'd posted that I realized the OP had offered his opinion explicitly, too, in that first entry.
