If that contract was 2-3 years smaller, the trade would have happened ages ago I think.
The last few years are truly a gamble no one is willing to take, retained salary or not.
I know. Although I do feel the risk/gamble has been exaggerated. Realistically it will be about 1.3M or less of cap recapture penalties of the Panthers. I don't think that's a huge problem, personally.
If he retires at 39 after being traded to FLA this offseason
Vancouver Canucks (2018-19 through 2021-22) $2,202,667
Florida Panthers (2018-19 through 2021-22) $1,380,667
If he retires at 40, this is how it breaks down
Vancouver Canucks (2019-20 through 2021-22) $2,936,889
Florida Panthers (2019-20 through 2021-22) $1,190,444
If he gets traded to FLA this offseason and retires at 41
Vancouver Canucks (2020-21 through 2021-22) $4,405,333
Florida Panthers (2020-21 through 2021-22) $0
I do think that Luongo and Tanev would be make the Panthers better next year as it seems goaltending and positional play by FLA's defenceman have been issues for Florida. As a package deal for peanuts, your team could do worse.
