Wouldn't surprise me if Luongo remained in Vancouver for a shortened season, if it were to happen I would expect him to be gone in the offseason.
I think Toronto is the most likely destination, and makes the most sense for both teams.
Florida is the destination of choice for Luongo, but it doesn't make much sense for Florida to acquire Luongo, thus it doesn't make much sense for Vancouver to move him to a team that probably isn't very likely of moving any decent pieces to acquire Luongo.
I feel like Luongo would be a great fit in Chicago, but I doubt the two teams will come together to make a trade involving a piece as big as Luongo, any time soon.
I also wouldn't rule out Luongo getting moved out at the Trade Deadline in a shortened season.
All things consider I believe Toronto to be Luongo's most likely destination.
