rules bickering aside (on that note, i like these trades since active owners should get a benefit)....
Shoot for what you can get. I think a Fleury and seguin for luongo, hossa and a 2nd is letting him off really lightly. Luongo is getting older, and honestly at this point i would much rather own fleury. hossa is past his prime and i have a hard time projecting over a ppg every again for him. Seguin still has elite upside and is really young.
I would think of it as how i would draft them (assuming standard 12 team roto):
Fleury- 2nd or 3rd rounder, solid #1 goalie, but there are a few i would rather have
seguin- 3rd rounder, very good winger now with elite upside
luongo- 5th rounder, question marks all over the place, and getting older
hossa- 6th round, just has not been elite in a few years, but still good
Since you are trading down so much, i would be targeting like a 2nd and 4th, or maybe even a first rounder.
