Wouldn't mind the Flames trading for Semin, under the the right circumstances of course. He has the potential to be a higher end Hudler. Best case scenario, the Flames would have two (semi) legit top six lines, with Bennett still being sheltered a bit.
Gaudreau-Monahan-Semin
Ferland/XXX-Bennett-Hudler
And if the Flames did end up regressing next season, it'd give them more leeway to trade Hudler at the deadline (ideally for a 2016 first).
Simplified base:
Raymond+Stajan/Jones for Semin+35th overall
We can go bigger:
Raymond+Stajan/Jones+3rd+Agostino for Semin+35th overall+McKeown
Why not ignore the Semin part of the trade, if we're talking 2nd round picks?
To Car: Hiller @ 50% retained (maybe plus a 3rd or 4th round pick?)
To Cgy: Ward + 35th overall
I would do this as well. Maybe instead of a pick, Flames add Reinhart or Hanowski if the Hurricanes want a player coming back.
Having a higher 2nd round pick might make trading up from 15th overall slightly easier too.
