Gostisbehere + Schenn + Provorov for Karlsson
Would be bad for the Flyers and I love Karlsson but you guys really want to see what Provorov becomes. Trust me the wait will be worth it and you guys are not winning any time soon so you don't need Karlsson that bad to push you over the top.
Plus the Ghost lit the league on fire last season you may want to hold on to see how good he is with more development.
