Wow, you're easily getting the best end of the deal of that one. You trade Duchene for Seguin, which is essentially an even swap (Duchene's better now, Seguin has slightly better upside). Sure, you could argue Duchene is slightly worth more then Seguin, but your robbing him in the second half. Dubnyk is not even guaranteed the starting job, and he's not the goalie of the future anywhere until he shows a lot more then he's shown. In return you get Vokoun and Neuvirth, essentially giving you a stud goalie on a winning team and guaranteeing you have one of the best young goalies in the league in Neuvy. You drop Conklin, and while I don't know the true value of the second round pick, I'd wager it's well worth it to upgrade your goaltending so much.
