I would probably dangle the players you're thinking of dangling -- Letang and Voracious. I would try and keep Backstrom just because I don't think 4.5 is bad at all. It would be hard trading away a player like Letang which is completely understandable, however you've definitely got to fill the hole at the goalie position. With Karlsson bouncing back nicely after a miraculous recovery time having him around for a full season next year seems a lot more likely than Letang who has a reputation for battling the injury bug the last few seasons. Your return for Letang and Voracek could be pretty handsome depending on who is hurting for a winger and/or offensive d-man. I would probably chase someone who's willing to part with a goalie like Rinne, or depending on how the play-offs fair for the caps, even Holtby as his SV% and W's were quite nice this year, or Rask. And trading someone like Voracek you might be able to swing a deal with perhaps your leagues Benn owner or or someone like Neal or Vanek and try to up your goals for the year. Not really sure any of those owners are willing to deal but if you're putting someone like Letang on the table, a lot becomes possible.
