I wouldn't be so sure that the Canucks will be the powerhouse that they were the last two seasons, nor would I be so sure that Florida would be in the position that you're assuming they'll be in. And you've gotta think that if Florida is in a bad position at the deadline, one of the bottom spots in the conference, perhaps, they might well just concede to run with their youth - namely, Jakob Markstrom. See what he's got. If they really suck, what's 34 year-old Roberto Luongo going to do for them, anyway? He couldn't lead them to the playoffs at 25, what makes you think it'll happen a decade later? Wouldn't it make more sense for them to give a highly-touted guy like Markstrom a shot, to grow with their other influx of good young players?
What I seem to be the only one doing is looking at the transaction from the other side's perspective.
Also, I wouldn't expect the Panthers to be at "the bottom of the conference". Not with the likes of the Isles, Leafs and Habs around. I would expect them to be fighting tooth and nail to finish with one of the top 8 point totals in the East. Considering they finished where they did on the strength of a ton of OTL points last year, I'd say they need all the help they can get.
